Study of 13 C NMR chemical shifts, 1, 13 coupling constants and T 1 measurements 13 C-H lead to reliable analysis of C NMR spectra of some phenyl acetates. Influence of some substituents on the electronic environment is reported. The variation of the chemical shifts resulting from different groups allows estimation of the additivity of the chemical shifts of the studied esters. This study confirms the existence of the additive nature of the substituent effect on aryl carbons of the phenyl acetates compared with monosubstituted benzenes.
