The preparations of tetra-alkylammonium salts of the [(C6H5)2SnCl3]−, [(C6H5)2SnCl4]2−, and [(C6H5)3SnCl2]− ions are described. Infrared spectra (1300–100 cm−1) and Raman (400–100 cm−1) spectra are reported and an assignment of the bands is made.

The infrared spectra of some tetramethyl-, tetraethyl-, and triethylmethyl-arsonium salts, and that of tetramethylstibonium triiodomercurate(II) have been recorded in the region 4 000 to 200 cm−1. Vibrational assignments are given for the quarternary 'onium cations, and comparisons are made with the spectra of alkylorganometallic compounds of germanium and tin.

The infrared spectra of the formate, acetate, and oxalate ions have been obtained for both the solid and aqueous solution. The Raman spectra of these ions with depolarization ratios have been obtained in aqueous solution. Vibrational assignments have been made which differ slightly for the acetate ion and more markedly for the oxalate ion from earlier work. The depolarization ratios confirm Fonteyne’s assignment for the formate ion.

The infrared spectra of tetrakis(dibutylamino) phthalocyanine and octakis(dibutylamino) compounds were studied via theoretical investigations. The results reveal deep fusion of the peripheral alkylamino moieties with the phthalocyanine chromophore in the tetrakis(dibutylamino)- but not in the octakis(dibutylamino)-phthalocyanine compounds. The successive localized molecular orbitals (LMO) and bond order analyses give support for the infrared vibrational results.

A number of different methods for preparing anionic Group 1B metal thiolate complexes have been investigated. The compounds [Me4N] [CU2(SMe)3] and [Et4N] [Ag5(SBut)6] are reported for the first time, and new methods for preparing the previously known compounds [Et4N] [Cu5(SBut)6], [Me4N]2 [CU5(SPh)7] and [Et4N]2 [Cu5(SPh)7] are described. The far-infrared spectra of the above compounds, and of CuSMe, CuSBut, AgSBut, [Me4N]2 [CU4(SPh)6] and [Me4N]2 [Ag5(SPh)7] have been obtained, and metal-sulfur stretching bands are assigned in the 150-350 cm-1 region. The low-frequency Raman spectra have also been obtained for some of these compounds. Possible structures for the new compounds are considered in the light of the low-frequency vibrational spectra.

The infrared spectra of substituted acetylacetonates have been discussed in the light of normal coordinate analysis of bis-(monothioacetylacetonato) Ni(II) assuming methyl groups as point masses. The Urey-Bradley potential constants evaluated are found to be quite close to those of analogous systems studied earlier. The calculations show that each of the fundamental bands results from vibrational modes involving appreciable contributions from a number of bonds. The single major contribution from the stretching of C = S has been found in the 723 cm−1 band. This is in agreement with the other conjugated systems, like thioamides, studied earlier.

Infrared spectra of crystalline complexes of N-methylacetamide (CH3CONHCH3) and of its ND analog with alcaline perchlorates, tetrabutylammonium halogenides, and alcaline halogenides have been investigated in NH stretching (3500–3050 cm−1), CO stretching (amide I, 1750–1500 cm−1), and NH bending (800–400 cm−1) regions. Possible structures for the complexes are proposed and the non-planarity of the amide group is discussed.
