Raman and infrared spectra and the structure of the dimethyl ester of 2,2,4,4-tetramethylglutaric acid

Abstract

Raman and infrared spectra of the dimethyl ester of 2,2,4,4-tetramethylglutaric acid in the solid and liquid states and the temperature dependence of the spectra were measured. The behaviour of some bands in the spectra indicates the presence of three conformers in the liquid state. Local order of the molecules due to dipolar interactions of ester groups was observed.
