The spectra and structure of sulphur-containing organic compounds-I. The vibrational spectra of dimethylsulphite and dimethylsulphite-d6

Abstract

The i.r. spectra of (CH3O)2SO in crystalline state and of (CD3O)2SO in liquid and crystalline states as well as the Raman spectra of (CH3O)2SO and of (CD3O)2SO in liquid state have been investigated. Two crystalline modifications of (CH3O)2SO and of (CD3O)2SO have been obtained. The i.r. spectra of oriented crystalline films have been investigated in polarized light. The vibrational spectra of (CH3O)2SO and (CD3O)2SO have been interpreted and their force fields obtained on the basis of more complete experimental data. © 1979.
