A vibrational analysis of ethylenimine

Abstract

Infra red and Raman spectra of ethylenimine are measured for the vapour and solid phases respectively. Assignments of fundamentals are made and the observed wavenumbers are compared with those predicted using the force field of cyclopropane. A force field is determined for ethylenimine which supports the assignments made here. Thermodynamic data for ethylenimine obtained using statistical mechanical methods is also reported.
