## Abstract Oxygen‐17 NMR spectra of 45 substituted methyl benzoates in acetonitrile were measured at natural abundance. The substituent‐induced chemical shifts (SCS) of the carbonyl oxygen correlate well with the σ~m~ and σ substituent constants in two separate correlations for __meta__ and __para
