Vibrational spectra and rotational isomerism in succinyl chloride

Abstract

From the infra-red spectra in the liquid state at 30°C and in solution in CS₂ and the Raman spectra in the liquid state at 30°C and solid state at –180°C of succinyl chloride, a vibrational analysis of the trans and gauche isomers of the molecules has been presented. The assignment confirms the earlier results of Nandy et al. The energy difference between the two isomeric forms of succinyl chloride is about 900 cal mol^–1(3762 J mol^–1).
