E. Perezruiz et al., VIBRATIONAL ANALYSIS OF GEM-DIMETHYLSUCCI NIC ACID AND ITS ALKALINE-SALTS IN AQUEOUS-SOLUTION, Canadian journal of applied spectroscopy, 38(6), 1993, pp. 163-170
The infrared and Raman spectra of the gem-dimethylsuccinic acid and it
s alkaline salts have been recorded in aqueous solution. An assignment
of the fundamental vibrations is proposed. The analysis of the polari
zation ratio suggests that the acid and its salts belong to the C(s) s
ymmetry point group.
