S. Yolou et al., VIBRATIONAL ANALYSIS OF GEM-DIMETHYLGLUTARIC ACIDS IN AQUEOUS-SOLUTION .2. 3,3-DEMETHYLGLUTARICACID AND ITS POTASSIUM-SALTS, Journal of Raman spectroscopy, 24(4), 1993, pp. 183-190
Raman and infrared spectra of 3,3-dimethylglutaric acid and its potass
ium salts in aqueous solutions (H2O and D2O) were recorded from 200 to
4000 cm-1. The analysis of the polariZation of the Raman lines indica
ted that 3,3-dimethylglutaric acid and its dipotassium salt belong to
the C2 group whereas the acid salt belongs to the C(s) group. An assig
nment of the fundamental vibrations is proposed.
