Abstract

The high-resolution stimulated Raman spectra of the ν2 and ν3 bands of C2H4 have been recorded and analyzed separately by means of the tensorial formalism developed in Dijon and Reims for X2Y4 asymmetric-top molecules. For the ν2 band, a total of 191 lines were assigned and fitted. We obtained a global root mean square deviation of 1.86 × 10-3 cm-1. For the ν3 band analyzed in interaction with the ν6 infrared band, a total of 185 lines were assigned and fitted. We obtained a global root mean square deviation of 1.29 × 10-3 cm- 1. Both analyses lead to very satisfactory synthetic spectra.
