820 BOOK REVIEWS [Analyst, Vol. 91 Book Reviews HIGH RESOLUTION NUCLEAR MAGNETIC RESONANCE SPECTROSCOPY. Volume 11. By J. W. EMSLEY, J. FEENEY and L. H. SUTCLIFFE. Pp. xxii + 666-1154. Oxford, London, Edinburgh, New York, Paris and Frankfurt: Pergamon Press. 1966. Price 105s. This is the second of a two-volume work covering the whole field of high resolution nuclear magnetic resonance spectroscopy to date, and is a worthy successor to the first volume. This second volume is devoted to showing how information concerning molecular structure may be deduced from n.1n.r. spectral parameters, and is not concerned with the theoretical basis of n.m.r. spectra, which was the main subject of Volume I. The first 200 pages of the book are accordingly devoted to correlations of lH resonance spectral parameters with molecular structure.The treat- ment is systematic throughout. The alkanes receive first consideration. Correlations of chemical shifts with electronegativities of substituent groups are prominent here. Magnitudes of spin - spin coupling constants in alkanes of ten provide information concerning bond angles. Thus, from genzinal coupling constants, H-C-H bond angles can be deduced, while from uicinal coupling constants, magnitudes of dihedral angles can be determined. Included in this section on alkanes are the spectra of various alkyl compounds as well as cycloalkanes and their derivatives. For cyclohexane and its derivatives, the importance of n.m.r. in distinguishing between axial and eqiratovial hydrogen atoms, thus greatly aiding configuration studies, is made particularly apparent.The next section of the book is devoted to the spectra of alkencs. The spectra of compounds containing vinyl groupings are first considered. The three magnetically non-equivalent hydrogen atoms in a vinyl group normally give rise to a highly coupled ABC spectrum. Full analysis of this system provides the chemical shifts of the three nuclei, together with the magnitudes and signs of the genzinal, cis and trans coupling constants. AMany correlations with these parameters have been made. For instance, chemical shifts have been related to Hammett o-constants and group dipole moments, geminal coupling constants have been related to H-C-H bond angles and cis and trans coupling constants to the electronegativity of a substituent X in CH, = CHX type compounds.Di-substituted and tri-substituted olefins make up the next two sections of thc book. Again, the treatment is comprehensive and a considerable amount of data is tabulated. On account of the near constancy of the geminal, cis and trans coupling constants towards different substituents in di-substituted olefines, n.m.r. spectra can often clearly distinguish between different geometrical isomers of the same compound. After a short chapter devoted to acetylenic molecules, the important subject of the n.m.r. spectra of aromatic molecules is considered. The effects of substitution on the ortho, meta and para hydrogen chemical shifts are fully discussed in terms of the relative contributions of inductive, resonance, diamagnetic anisotropy and electric-field effects.Good linear correlations of para lH and 13C chemical shifts with Hammett a-constants are found but only when all intermolecular effects on shielding have been eliminated by examining samples in very dilute solutions in inert solvents. In di-substituted benzenes the substituent effects on the chemical shifts of the ring hydrogen atoms can, in general, be shown to be additive. The authors then discuss the spin - spin coupling constants in aromatic molecules. These, unlike the chemical shifts, are fairly independent of the substituents and, as might be intuitively expected, are such that JortlLo J , n e f a > J p w r c r , and all have the same relative sign. Heterocyclic molecules are the subject of the next section of the book and this is followed by a chapter devoted to “large complex organic molecules.” Included under this heading are alkaloids, steroids, fatty acids, amino-acids, peptides and other miscellaneous compounds.Here the authors have been content simply to summarise briefly the most important work on these species of compounds. This is reasonable in view of the large amount of data now available, but the book does suffer a little in this section from its lack of detail. The first half of the book ends with a chapter devoted to miscellaneous lH resonance studies, which includes spectra of paramagnetic species, polymers and studies of medium effects in liquids. Pride of place is inevitably given here to 19F resonance studies. The widespread interest in fluorine chemistry is made abundantly clear from the vast amount of laF spectral data now available.The large 19F chcmical shifts compared to 1H shifts cause I9F spectra, in general, to be less strongly coupled than lH spectra, thus making spectral analyses less arduous. Spin coupling constants for F-F coupling are also considerably larger in general than the corresponding H-H couplings. However, their variation with spatial proximity and inter-bond angles are far less predictable The second half of the book deals with n.m.r. studies of nuclei other than hydrogen.December, 19661 BOOK REVIEWS 82 1 than the H-H coupling constants. This is apparent in the discussion of the many types of fluorine compounds where numerous apparently anomalous F-F coupling constants arise.The treatment here is very comprehensive and reflects the authors’ particular interest in 19F resonance work. The various types of fluorine compounds are treated systematically and the important r6le that n.m.r. has played in establishing the structures of fluorine compounds is well in evidence. The remainder of the book is devoted to spectra of other magnetic nuclei apart from hydrogen and fluorine. The varying amounts of space devoted to these nuclei reflect, to a large extent, the relative importance of these nuclei from the point of view of chemists who use the n.m.r.technique. Thus, IlB, 13C and 31P receive detailed coverage, whereas other nuclei such as 14N, 1 7 0 , 2gSi and 59C0 are mentioned much more briefly. This volume will most certainly be used as an important reference book on n.m.r.spectral data. Its usefulness in this r61e is particularly enhanced by the inclusion of six appendices setting out further data in the form of tables and charts. Included in these appendices are a table of pvalues of many organic compounds based on the data of Tiers, charts of ‘H chemical shifts and coupling constants of a wide variety of chemical groupings, a table of substituent shielding effects in benzenes and a comprehensive table of 31P chemical-shift values. The amount of data contained within the covers of this book is vast, and it comes as a surprise to find that the book is only 490 pages in length. In order to achieve such compression of subject matter the authors have organised their material well and presented much of the data clearly in tabular form.Another good feature of this book (and also Volume I) is the very large number of spectral traces reproduced. This certainly is a great aid to reading a book of this type. The price of the book may seem rather high for its moderate length, but the amount of data presented therein, and the great use to which this book will inevitably be put by all practising n.m.r. spectroscopists, make i t well worth the money. K. G. ORKELL ANALYSIS OF THE NEW METALS-TITANIUM, ZIRCONIUM, HAFNIUM, NIOBIUM, TANTALUM, TUNG- STEN AND THEIR ALLOYS. Pp. xii + 275. Oxford, London, Edinburgh, New York, Toronto, Paris and Braunschweig : Pergamon Press. 1966. Price 60s. This monograph represents a considerable expansion of Messrs. Elwell and Wood’s earlier publication “The Analysis of Titanium and Zirconium” as it includes methods for the analysis of hafnium, niobium, tantalum, tungsten and their alloys, and revised methods for titanium and zirconium.The authors state in the preface that their book is intended as a laboratory compendium containing essential information for the satisfactory analysis of titanium, zirconium, hafnium, niobium, tantalum, tungsten and their alloys, rather than a treatise on the analytical chemistry of these metals. However, the authors do go to the trouble of giving a useful summary of the analytical considerations involved with each determination, including comments that should pilot the analyst clear of most of the pitfalls] associated with new techniques. For example, it is extremely useful for the practising analyst to receive such detailed guidance, as in the case of the polarographic determination of tin and lead, that “The addition of 2 ml of potassium ferro- cyanide solution (2%) prevents the interference of more than 200 ppm of copper or 600 ppm of molyb- denum.” The very full description of the oxide - resin technique for the determination of the impurities in zirconium is typical.All equipment. is fully described and the treatment of samples and preparation of standards is treated with unusual thoroughness. Weights, volumes and all information necessary for the prosecution of a successful analysis are present. Sampling, a subject often omitted from books of this type, is covered in the introduction and includes not only methods of sampling for massive metals but also for special materials such as titanium sponge and granules.Recommendations are made for machining and drilling samples of these reactive metals with a minimum of contamination. The authors are to be congratulated on the meticulous manner in which this monograph has been written and arranged. I t is obvious that a tremendous amount of thought and care has gone into the making of this book. This effort is apparent in every aspect of the book and extends to the important but often neglected index and contents list. All analysts with an interest in these less common metals will appreciate the efforts of their two colleagues in making available such useful and important knowledge. By W. T . ELWELL and D. I?. WOOD. Much invaluable detail is also provided for spectrographic procedures.G. L. MILLER822 BOOK REVIEWS [Analjst, VOl. 91 POLYSACCHARIDES, PEPTIDES AND PROTEINS. Volume 4. By R. T. COUTTS and G. A. SMAIL. This small volume, well bound in soft-back style, forms the fourth of a series of Pharma- ceutical Monographs under the general editorship of Professor J . U. Stenlake of the University of Strathclyde. I t is in two parts: the first 72 pages by R. T. Coutts of the University of Saskat- chewan deal with the polysaccharides of pharmaceutical interest, and the remainder of the book, by G. A. Smail, gives, in an admirably concise way, an up-to-date outline of the chemistry of polypeptides and proteins. The authors handle their subject matter in tutorial style, and the book is primarily intended as an adjunct to honours undergraduate courses in pharmacy.However, it provides an extremely readable introduction to protein and polysaccharide chemistry and is to be recommended, not only to undergraduates, but also to workers in related fields who may wish to acquire an under- standing of the basic chemical and physical properties of these biological polymers, without going too deeply into detail. The five chapters on polysaccharides provide an admirable summary of the properties of most of the common polysaccharides likely to be of interest to the pharmacologist, but it is a little surprising to find that although hyaluronic acid, chitin and the blood group substances are described, there is no mention of chondroitin sulphate or keratan sulphate.The fifth chapter on the somatic antigens of gram-negative bacteria is so short as to be of little value except as a reminder of the existence of this important class of compounds. The section (120 pages) dealing with the proteins and peptides is quite excellent, and provides an adequate introduction to general protein chemistry, as well as concise and useful accounts of the polypeptide and protein hormones of pharmaceutical value. The last chapter contains a useful summary of information about the more important polypeptide antibiotics. Pp. x + 209. London: William Heinemann Medical Books Ltd. 1966. Price 30s. s. M. PARTRIDGE THE SEPARATION OF BIOLOGICAL MATERIALS. BRITISH MEDICAL BULLETIN. Volume 22, No. 2. May, 1966. Edited by R. A. KEKWICK. Pp. 103-194.London: Medical Department; The British Council. 1966. Price 30s. Although the title suggests that this number of the British Medical Bulletin will be mainly of importance to the biochemist and medical research worker, this volume will, in fact, be of inestimable value to the analyst, reviewing, as it does, major advances that have been made in the separation of the materials of which the cell is composed. Fifteen to twenty years ago the powerful separations possible by chromatography were replacing the relatively simple methods of precipitation, partition and other physical and chemical techniques that were the main armamentation of the analyst, and which usually demanded analytical methods specific for the substances to be measured. With the newer methods described in this monograph, many sub- stances closely resembling one another in their chemical properties may be separated so completely that they can be determined by non-specific means. This is particularly clearly illustrated by the modern techniques of analysis of amino-acids, which are determined by the ninhydrin reaction after separation on columns.In gas chromatography, there is separation of micro or millimicro- gram amounts of material which are detected and determined by wholly non-specific detectors such as by argon or flame ionisation, electron capture or katharometry. Such methods are already widely used by the clinical chemist, and their application to the problems of other analysts is already in progress. This volumc provides concise, critical reviews o f the theory and practice underlying all of the recently developed methods of separation.After a theoretical account of the physical chemistry of porous systems by Ogston, the practical applications are dealt with by Andrews in his account of gel filtration (or exclusion chromatography), and by McUougall and Synge who discuss electro- phoresis in gels. Ultra-centrifugation in a solution with a density gradient has provided an im- portant technique for separating sub-cellular particles, viruses, proteins, nucleoproteins and nucleic acids. This technique has played an important r81e in the purification and concentration of viruses for vaccine production, and is of particular importance when used in conjunction with sensitive assays or isotopic labelling experiments.These techniques have thrown light on our knowledge of the structures of the haemoglobins and various peptides and protein hormones, and also on the mechanism whereby nucleoproteins provide the basis of heredity. By such methods genes have been found to control synthesis of proteins and enzymes and indirectly, therefore, of all biological materials. There are also excellent accounts of the separation of the nucleic acids, of viruses, of proteins and protein sub-units, and of peptides and of amino-acids. The reviewsDecember, 19661 BOOK REVIEWS 823 of gas - liquid chromatography by Scott, of the separation of lipids by Nichols, Morris and James, of peptides by C. J. 0. R. Morris, and of carbohydrates and related substances by Northcote are likely to be of the most practical importance to the practising analyst.Mathias has reviewed especially well the application of a variety of these methods to the separation of sub-cellular particles. These methods are primarily of concern to biochemists investigating the nature and behaviour of highly labile substances and structures under dynamic conditions, and for them this new volume of the British Medical Bulletin will be unequalled. To the practising analyst there may well be much that is new, and it can confidently be recommended that this volume should be on the shelves of all analysts. The scientific editor, Professor R. A. Kekwick, and the British Council are to be congratulated on this excellent volume, which is a bargain a t 30 shillings. C. H. GRAY INFRARED BAND HANDBOOK SUPPLEMENTS 3 AND 4.Edited by HERMAN A. SZYMANSKI. Pp. Supplements 3 and 4 contain nearly 5000 bands over the range 2 to 2 5 p , bringing the total number listed in the original Handbook and its supplements to over 18,000. All the results collected for the present volume have been published between 1962 and 1964, and the assumption is made that very accurate, high resolution instruments have been used to obtain such data. Although this assumption may not be fully justified, the suggestion that spectral bands of an unknown compound need only be compared with published data within 5 cm-l is probably a fair one. The mode of presentation of the bands in decreasing wavenumbers is convenient, and in- formation concerning the structural formula of the compound, its physical state and the more important instrumental conditions is easily accessible.The main criticism of the book (and its predecessors) is its possible superfluity in a field where spectral documentation is already in an advanced state. Dr. Szymanski has undertaken a mammoth task in preparing these volumes and doubtless feels committed to the publication of many more in the years to come, but the question which surely must be in the minds of most practising spectroscopists is “Will it all have been worthwhile ?” xvi + 261. New York: Plenum Press Data Division. 1966. Price $15.00. D. A. ELVIDGE SUBMICRO METHODS OF ORGANIC ANALYSIS. By RONALD BELCHER, D.Sc. Pp. x + 173. 1966. Price 55s. This latest contribution by Professor Belcher to the analytical chemists’ library is a neat little book-nicely dedicated to Sir Harry Melville and Professor Maurice Stacey, who did so much to encourage the development of the Birmingham School of Analytical Chemistry (would that there were others similarly inclined in British Universities !) .Written in Belcher’s customary clear, concise style, the text is strongly practical in outlook. Indeed, its synopsis claims that “workers will find here, for the first time in book form, all they need in order to apply the techniques in their own laboratories”-with what initial degree of success is, regrettably, not specified : experience with manipulations on the submicro scale is necessary for success. Nevertheless, for students and analysts of all ages, anxious to set about starting to acquire the necessary experience, this is the book; filled with useful practical detail, it is an essential distillate of the practical experiences of Professor Belcher and his co-workers in this field.An interesting introduction is followed by useful sections dealing with the submicro balance and with the general apparatus required for submicro work. Chapters are then devoted to the methods recommended for determining each of the following elements or functional groups : nitrogen ; carbon and hydrogen ; chlorine ; bromine and iodine ; fluorine ; sulphur ; phosphorus and arsenic ; carboxyl ; organic bases in non-aqueous media ; alkoxyl and N-methyl ; acetyl ; carbonyl ; olefinic unsaturation ; nitro ; nitroso ; and thiol ; and other chapters deal with periodate oxidation and with the cryoscopic determination of molecular weight.Much of the work described in this text-book has already been published and, to those of us who have followed the published accounts of Professor Belcher’s studies as they progressed, this book must, a t first sight, appear to be rather an expensive way of acquiring reprints. The text, however, incorporates improvements to some of the earlier procedures and gives additional details that have not been published; to anyone starting off on the submicro scale this is the sort of book that is cheap a t any price. Amsterdam, London and New York : Elsevier Publishing Company Ltd.824 BOOK REVIEWS [Analyst, VOl. 91 It is to be hoped that this timely compilation by Professor Belcher will lead to increased interest in the methods he has pioneered-methods that deserve more interest than has been shown in recent years.The importance of the submicro scale and Belcher’s contributions have yet to be realised in full. NOBEL LECTURES: CHEMISTRY, 1922-1941. Pp. xii + 508. Published for the Nobel Foundation. 1966. Price 160s. As is known, by the publishing arrangement between the Elsevier Publishing Company and the Nobel Foundation, the Nobel lectures are now becoming available in the English language. This present volume includes the presentation addresses, the Nobel lectures given by, and the biographies for, each Nobel Laureate in Chemistry from 1922 to 1941, for each year in which the award was given. It is difficult to review this book because these lectures are often the foundation on which the author’s chemical education is based.To the analytical chemist this period includes three lectures that should hold his attention. They are Aston’s lecture on Mass Spectra; Pregl’s lecture on Quantitative Micro-analysis of Organic Substances ; and Debye’s lecture on Methods to Determine the Electrical and Geometrical Structure of Molecules. Richard Kuhn, the Nobel Prize winner in 1938, was unable to accept his medal until 1949, and we are, therefore, denied the honour of his lecture. Of great interest are the many contributions that Kuhn and his school made to the perfection of chromatographic methods for the isolation of carotenoids. It is of interest to speculate on the use that modern methods of analysis, e g . , gas - liquid chromatography, would have been to, say, Winhaus in the constitution of the sterols, or his pupil Butenandt on sex hormones.The book is recommended to all those who have interest in learning how chemistry has evolved in the last 4 decades. All of life is here, because often a few discreet words describe the tragedies of our civilisation. The volume is beautifully printed, and exquisitely produced, although to the ordinary reader its price is prohibitive. However, we should expect to find i t on the shelves of all good libraries. D. M. W. ANDERSON Amsterdam, London and New York: Elsevier Publishing Company Ltd. G. NICKLESS ANALYSIS INSTRUMENTATION-1965. Proceedings of Eleventh Annual Analysis Instrumentation Symposium held May 26-28, 1965, a t Montreal, P.Q., Canada.Edited by L. FOWLER, R. G. HARMON and D. K. ROE. Pp. viii + 240. New York: Plenum Press. 1966. Price $12.50. The pattern of previous years (Analyst, 1965, 90, 639) is repeated in this volume, in which 21 papers presented a t the Montreal Symposium are printed. The topics are very diverse: of the eight sections the largest contains four papers, while in one section a dissertation on writing instruction manuals for instruments adjoins a description of a miniaturised gas chromatograph - mass spectrometer for a space mission to analyse the soil on Mars. Although this diversity certainly reflects the breadth of interest in instrumentation it is unlikely to encourage compulsive buying of the volume by laboratories with restricted interests. Printed by photolitho from typescript, the volume contains rather less material than a single issue of a normal journal, and so must be rated as extremely expensive.Publication time has lengthened from the not unreasonable 9 months of the previous issue to 12 months. No discussion-often held to justify this form of publication-of the papers is reported. To quote from thc foreword, “The editors of this volume, Messrs. Harmon and Roe, spent many long hours of tedious labour.” They have done a good job, but to what end? Good papers which should be in the open literature, accessible to all, are obscured in a publication that few can afford and fewer would read. Ephemera and trivia need not be recorded. It is said that this form of publication provides a necessary end product to a symposium, one which a conferee can take back to his employer as an earnest of his attendance and the benefits arising therefrom, and a return for the payment of his expenses.Continuing the previous quotation from the foreword, “Without the willingness of the authors to prepare the reports of their work, neither the symposium nor the book would have been possible. Our first and strongest thanks must go to them.” There should also be added the willingness of the authors to deny them- selves the appearance of their work in the acknowledged journals and its dissemination in the abstracting journals. The present volume contains fewer papers but of a more uniform quality than the previous volume. I can find nothing to justify publication in the present form. A costly memento.E. BISHOPDecember, 19661 BOOK REVIEWS 825 ANALYTICAL CHEMISTRY OF SELECTED METALLIC ELEMENTS. Pp. xiv New York: Reinhold Publishing Corporation; London: Chapman & Hall Ltd. The elements discussed in this booklet are the alkali metals and alkaline earths, aluminium, antimony, arsenic, bismuth, cadmium, chromium, cobalt, copper, iron, lead, magnesium, man- ganese, mercury, molybdenum, nickel, silver, tin, titanium, tungsten, uranium, vanadium and zinc. The author, who has been concerned for many years with the teaching of analytical chemistry a t the University of Harvard, explains in his preface that it is his express aim to provide an introduction rather than a comprehensive account of the analytical chemistry of these metals. In it he hopes to provide a feeling for the individual characteristics of each metal by providing a factual account of the chemistry and physical properties upon which all of the classical and physico-chemical analytical properties are based. Unquestionably he has succeeded.This is a book that will be found useful by all students of analytical chemistry in the age group 16 to 60. In each individual monograph the text usually offers information on the physical properties of the metal itself, on its various ionic species, its electrochemical potentials, tendency towards complex formation, oxides and common salts, methods of separation from other elements, reactions with organic reagents, recommended method of analysis, gravimetric, titrimetric and physico- chemical (most frequently electrochemical).There are many flashes of humour in the text, e.g., in describing the Marsh test . . . “the very sensitive test for arsenic immortalised by A. Conan Doyle with the able assistance of Sherlock Holmes,” . . . followed by references to “Arsenic and Old Lace’’ and “who dunit” literature. In another chapter we find, “Aluminium hydroxide exists only on the blackboards of chemistry classes,” . . . and so on. These leaven the text well when it might otherwise become indigestibly heavy because of its concentrated texture. At the same time it must be observed that there is sometimes a looseness of terminology about the text that gives the impression that we are dealing with transcribed lecture notes rather than conventionally produced text, e.g., ions are generally written as M+++ but occasionally as M+n and even Mn+ (page 71).Similarly, the terminology “homogeneous precipitation” is placed in cautionary quotes on page 15 whilst on page 16 it is correctly used as “precipitation from homogeneous solution” and then a few lines subsequently as (the physically impossible) “homogeneous precipitation,” this time without quotes. The author defends his use of “ + 5 uranium” and so on in place of “uranium(V)” etc., in his preface, but this does go against international usage, and although one appreciates the difference between “cc” and “ml,” use of the former again goes against modern practice. Similarly, the use of the word “complexone,” defined expressly as “a complexing agent,” on pages 46 and 47 is not generally accepted. English students will also have to resist the author’s use of the split infinitive though it is frequently rather attractive. These are, however, subjective minor criticisms of an attractive and worthwhile booklet, that will undoubtedly be of considerable service to students of analytical chemistry in all walks of the profession.

New York, London and Sydney: John Wley and Sons. 1966. Price 23s. This book is a compilation of problems in general chemistry and qualitative analysis, aimed initially, it is supposed, a t students of Washington State University. Frankly, this book is suitable only for use in schools in this country, to advanced and scholarship levels. What is interesting is the approach to the topic, and it provides a comparison with the books used in this country for this level of teaching. The book is divided into chapters; in each chapter the principles for solving each given type of problem are given first, followed by examples of problems in which these principles are used. Each chapter is completed by a series of examples, the answers being given in an Appendix. Naturally, problems are arranged in order of increasing difficulty. A detailed discussion of significant figures is given in another Appendix, as well as a review of fundamental mathematical operations. This book can be recommended as an interesting facet of the educational system in chemistry of the TTnited States. G. NICKLESS
