REVIEWS OF BOOKS 3 649 producing the book is said by the authors to be " the fceling that our good fortune in acquiring a large mass of previously inaccessible data leaves u s with an obligation to collect this into one place for ease of access ". Certainly. to have so many spectra brought together in one volume is most valuable, the more so since many of them have not previously been published. The molecules whose spectra are presented range from triatomic to naphthalene and even bigger molecules. There are short introductory accounts of the underlying theory and of the experimental methods, but the bulk of the book is devoted to showing and interpreting the spectra, molecule by molecule. For each molecule, the full photoelectron spectrum is shown first; and then, under higher resolution, each " band " in the full spectrum.The book is intended to be a reference work for research workers. As such it will be invaluable to anyone interested in the electronic spectra of molecules and ions; and, indeed, to anyone interested in molecular orbitals, for whatever purpose. With its hundreds of excellent line drawings, the book as a whole can be said to be well produced. There are, however, signs of too hurried preparation. Thus on page 6, figs. 6.23, 6.26 and 6.27 are stated to refer to the spectra of diacetylene, cyanoacetylene and cyanogen; but in fact the figure captions make it clear that the figures refer to acetylene-d2, diacetylene and cyanoacetylene respec- tively. The text appears not to have been checked quite as carefully as it should have been.Othei errors, not entirely trivial, lead to the same conclusion. Thus (lb2)2 is written in error for (lb# (p. 78, line 7); lB1 is written in error for 2B1 (p. 77, table 4.4; p. 79, table 4.6; p. 81, table4.7); (1b)2 is in error for (lb1)2 (p. 81, line -2); v1 is in error for v2 (the bending vibration of SO,; see p. 85); and lxU is in error for lxu (p. 170). On p. 87 (line 18), nitrous oxide is writtenin error for nitrogen dioxide; NO+ is in error for NO: (line 2); and 124" is written by mistake for 134". A little more time spent on proof reading would have eliminated these and other blemishes. A. D. WALSH Received 25th June, 1971 Chemistry of Complex Equilibria. By M. T. BECK. (Van Nostrand Reinhold Co., London, 1970.) This book, one of an analytical chemistry series, has the admirable aim of giving a broad and realistic account of complex equilibria in solution in which the chemistry is not hidden behind algebraic equations.Anyone who has but glanced at the Chemical Society publication StabiZity Constants will appreciate that this is a formidable task, especially when topics such as mixed ligand, protonated and polynuclear complexes are rightly treated in some detail. Even neglecting problems concerned with the rates of attainment of equilibria, the complexity of the composition of many common and important solutions such as those of aluminium salts or of silicates in water is depressing. There are no entirely satisfactory methods of species identification, and the physical significance of the numerous equilibria which have been postulated for such systems is highly suspect.The Hungarian author has a readable style with some entertaining asides, e.g., " Rediscovery is a fairly frequent phenomenon now ", " Sometimes a linear relationship is assumed between the price of the instrument and the value of the information obtained by its means "; he has obviously actually read many of the historically important papers which he cites, and the literature references are less exclusively Anglo-Saxon than is often the case. In some places, however, references are catalogued with little evaluation. There is a curious and basically unhealthy dichotomy in the subject between those who label themselves " inorganic " or " co-ordination " chemists, who are primarily interested in speci identification and the equilibria between them, and '' physical " or " electrolyte solution " chemists who lay emphasis on the quantitative description of physicochemical properties in general.This book is of the co-ordination chemistry variety. For example, conductivity measurements are rele- gated to a reference to C. W. Davies under " miscellaneous methods", the information obtainable from osmotic coefficient measurements is only briefly mentioned in the context of some eutectic systems, and the problems which arise from lack of knowledge of ionic activity coefficients or their variations with solution composition are largely avoided. Although in the reviewer's opinion an outstanding book which treats both the methods and the results of stability constant determinations in a readable and compact manner is still to be written this is a useful attempt.Life and earth scientists who refer to it will readily appreciate the reasons for the stark contrast between the elegant simplicity of the standard text-book treatment of simple acid- base and complex-ion equilibria, and the remarkably unhelpful replies they are likely to get from chemists to questions about the chemical equilibria in physiological fluids and natural waters!

Emeleus, D.Sc., A.R.C.S., F.R.S.*PROFESSOR OF INORGANIC CHEMISTRY, UNIVERSITY OF CAMBRIDGE)and J. S. Anderson, Ph.D., A.R.C.S., F.R.S.(DIRECTOR, NATl ONAL CHEMICAL LABORATORY)In preparing the third edition of this bookthe authors have attempted to make the subject matterreflect the present state of knowledge andthe most important developments in inorganic chemistry.The choice of topics for discussionis necessarily somewhat arbitrary.Furthermore, some fields of inorganic chemical research-for example boron chemistry, the theoryof co-ordination compounds, organometallic chemistry-are so productive of new knowledgethat it is impossible to do full justiceto recent progress in the whole subject.Nevertheless, it is hoped that this new editionwill give the reader some picture of developmentsduring recent years in our knowledge,our theoretical outlook and our understandingof the chemistry of the elements.The authors ask that the book be read critically,and that where possible the text should be supplementedby reference to the more important original papers.The book is written primarily for Honours students,research workers and teachers,but will also interest the Scholarship candidate in schools.35s.ROUTLEDGE & KEGAN PAULiIntroducing an important and authoritative encyclopediaTHE INTERNATIONAL ENCYCLOPEDIA OFPHYSICAL CHEMISTRY AND CHEMICAL PHYSICSEditors-in-ChiefE.
