Summary

The Raman spectra of cinnamyl alcohol and cinnamyl acetate are re-investigated and their frequencies compared with those of ethyl cinnamate. A great similarity between the spectra of all these substances is observed. The higher C=C and C=O frequencies in cinnamyl acetate and allyl acetate as compared with ethyl cinnamate and ethyl acrylate is explained as due to the existence of resonance in the latter. It is pointed out that when comparisons are effected carefully the C=C and C=O bonds mutually weaken each other when they exist in conjugation.
