Raman effect and chemical constitution

Influence of constitutive and other factors on the double bonds in organic compounds Part III. Effect of the benzyl group on the C=O bond in esters

Raman spectra of esters containing the benzyl group, (i) benzyl esters of various acids and (ii) esters of phenyl acetic acid derived from different alcohols, have been investigated. Data relating to other carbonyl compounds such as ketones, aldehydes and acid chlorides have been collected. In regard to its influence on the C=O frequency the benzyl group is found to resemble closely alkyl groups and to differ markedly from the phenyl. This confirms the views already expressed in Part II and establishes that the C=O group is influenced mainly by the electromeric effect. The introduction of an additional CH2 prevents the transmission of this effect.
