The Raman and Infrared Spectra and the Structures of Dimethyl, Methyl Germyl and Digermyl Sulfide

Abstract

Abstract The Raman and infrared spectra of dimethyl sulfide (CH3−S-CH3) have been assigned in terms of a D3d model1. The structurally related compounds, digermyl sulfide (GeH3−S-GeH3) and methyl germyl sulfide(CH3−S-GeH3) are prepared according to the literature2–4, and their vibrational spectra are measured. The analysis of these spectra comparing with those of CH3−S-CH3 allows us to determine the molecular structures to be D3d for GeH3−S-GeH3 and a C3v for CH3−S-GeH3 with a linear—S—.
