Analyse Vibrationnelle et Structurale en Série Aliphatique Saturée. II —Spectres de Vibration de l'Acide Succinique et de ses Sels Alcalins en Solution Aqueuse

Raman and infrared spectra of succinic acid (CH 2 COOH) 2 , (CH 2 COOD) 2 and its alkaline salts KH(CH 2 COO) 2 , KD(CH 2 COO) 2 and K 2 (CH 2 COO) 2 in aqueous solution have been investigated from 3500 to 400 cm −1 ; an assignment of the fundamental vibrations is proposed. The analysis of the polarization ratio leads us to conclude that the neutral salt belongs to point group C s . The acid salt and the acid itself belong to point group C 1 and do not exhibit intramolecular bonding.
