Carbon‐13 NMR spectra are reported for 69 substituted methyl benzoates in deuteriochloroform or in its mixture with dimethylsulphoxide‐d6. The substituent‐induced chemicalshifts (SCS) of the CO carbon correlate poorly with dual substituent parameters (DSP) in all possible modifications, and for meta derivatives in particular this correlation is both overpara meterized and imprecise. A much better
