The new antimony(V) anions SbCl5Br−, SbCl3Br3− and SbClBr5− have been isolated as their tetraethylammonium salts. The vibrational spectra of these compounds and of Et4NSbBr6, (NH4)2SbBr6, Et4NSbF4Br2 and SbBr5, OEt2 are reported and interpreted

The molecular structures of dimethyltrifluorophosphorane, (CH 3 ) 2 PF 3 and trimethyldifluorophosphorane, (CH 3 ) 3 PF 2 , have been investigated by analysing the vapour-state infra-red spectra (200–4000 cm −1 ) and liquid state Raman spectra (5

Examination of the infra-red and Raman spectra of the compound (CH 3 ) 2 N 4 BH strongly supports the assignment of a cyclic azo-type structure having C 2ν symmetry. The spectra are analysed in terms of the vibrations expected of such a molecule.

The infra-red spectra of the thiocarbonyl derivatives SCF 2 and SCCl 2 are described; a study of the band contours and branch separations, together with a comparison of the vibrational spectra of related compounds, confirms a preliminary assignment f

Cryoscopic measurements on aqueous solutions containing bis(trifluoromethyl)mercury, Hg(CF 3 ) 2 , and chloride, bromide or iodide ions indicate the formation of labile 1:1 adducts, for which approximate formation constants have been derived. The res

The vapour phase infrared and liquid state Raman spectra of the mono-substituted fluorophosphorane, CH 3 PF 4 , have been recorded. Analysis of the spectra is complicated by the facts that (1) the CH 3 PF 4 molecule is nearly a spherical top, and (2)
