Raman Spectrum and Vibrational Assignments of Gaseous Dimethyl Ether

Abstract

The Raman spectrum of gaseous dimethyl ether has been obtained and that of the liquid reinvestigated. In the low‐frequency region of the gas spectrum, two bands have been observed which are attributed to overtones of the torsional motions of the methyl groups. The assignment of vibrational frequencies is discussed on the basis of a C_2v symmetry in the molecule.
