摘要:

Infrared spectroscopy has rarely been used to study inorganic reactions in the solid state in spite of its advantage that reactants and products can quantitatively be monitored throughout the course of areaction. Manzelli and Taddei1- found that KMnO4reacts in alkali iodide matrices to yield IO3−and MnO2as products, but no spectra of the reaction products were presented Gymkowski, Lamhert, and Kimmel2showed that IO4−is the initial product, which then decomposes to IO3−. At 100°, KMnO4reacts in a KBr diskt o give Br2and MnO2.3

摘要:

The procedure is described for the determination of the analytical line pairs honology. It is based on the succesive testing of the scatter diagram parmeters and on the comparison of the orthogonal regression coefficient value with the temperature and concentration fluctuation coefficients value. The cri terion for the resul ts of testing is the increase of the accuracy of the determination of the concentration by using the reference line method. This is done in the final stages of the procedure.

摘要:

An expression for the maximum increase in signal to noise ratio obtainable with a pulsed hollow cathode lamp as primary source for atomic fluorescence measurements is derived under certain assumptions. Experience with copper and calcium hollow cathode lamps showed that by using these lamps in the pulsed mode in conjunction with a gated detector, the increase in signal to noise ratios obtained are less than a factor of 5, due to self-absorption broadening of the primary source emission lines.

摘要:

The complete mass spectral fragmentation patterns of naturally abundant diethylmonogermane and diethyldigermane are presented. The base peaks of both diethylmonogermane and diethyldigermane occur in the envelopes of peaks in the GeC2H+x=O→7 region at m/e 104 and m/e 103, respectively, and not in the parent regions.

摘要:

Band splitting can be observed in the infrared spectra of metal complexes arising from the naturally occurring mixture of isotopes, and the use of these splittings in assigning metal-ligand vibrational modes is described.

摘要:

This communication is concerned with atomic emission of the 589.0/589.6 nm sodium doublet, in a N2/H2diffusion flame on the sheathing gas box of a carbon filament atom reservoir. The sample is directly atomised by the carbon filament thechnique1.

摘要:

The oxygen atom of dimethylformamide (DMF) is a good electron doaor site and in a proton donor solvent the solute-solvent interactions would include hydrogen bonding at this site. As this hydrogen bonding is expected to be relatively strong, it would predominate when both the lMF and the protonic acid are present at very low concentration in a solvent such as carbon tetrachloride, and the effect of this hydrogen bonding on the proton chemical shifts and coupling constants i n LMF can be observed. If the protonic acid is aromatic, such as phenol, and is in excess of the LMF, other form(s) of solut-olvent association would become significant and give rise to aromatic solvent induced shifts (ASIS), which would obscure the effect of hydrogen bonding at the oxygen site of the MF. The ASIS in DMF are well known, and the shifts have been attributed to the diamagnetic ring current effect of the aromatic solvent and specificsolut-olvent association.1More recently, the ASIS has been interpreted as the result of time-averaged general solvation around the polar site of the solute.2
