ResumoThe Raman spectra and polarization parameters of the liquid dimethyl chalcogenides, CH3-X-CH3 (X = 0, S, Se, Te) and the infrared spectra of the gaseous compounds1 have been measured; analysis of these data allow us to deduce much information about the molecular structure. The observed band contours, band types, simplicity of the spectra and the mutual exclusions in the Raman and infrared, are in excellent agreement with the theoretical expectations for a model of D3d symmetry, with a linear C-X-C skeleton. The proton NMR spectra of the molecules CH3-X-CH3 show only one signal.
