Assignment of the raman frequencies of methyl and ethyl benzoates and ethyl cinnamate

Abstract

The Raman spectra of methyl and ethyl benzoates, and ethyl cinnamates have been recorded in the liquid state at 42° C. Some new lines are reported. The lines at 1181, 1280 and 1724 cm.−1 in methyl benzoate, and 1172, 1278 and 1719 cm.−1 in ethyl benzoate are assigned to the group and 1205, 1270 and 1639 cm.−1 are assigned to the group in ethyl cinnamate.
