Infrared and raman spectra of vinylene carbonate

Abstract

The infrared and Raman spectra of vinylene carbonate have been observed from 50 to 4000 cm-1 and most of the fundamental modes of vibration have been assigned. The B2 ring-puckering vibration is at 258 cm -1 in the liquid, in good agreement with the results of microwave intensity measurements. A short C-O bond length, on the order of 1.15-1.17 Å, is indicated by the high frequency of the carbonyl stretching frequency.
