Notes: Measurements are reported on the nuclear magnetic resonance spectra of the acetyl protons of a series of substituted acetophenones. Although the extreme values of the chemical shifts, δCOCH3 for the meta- and para- substituted compounds differ only by 0·2 units, the values themselves are linearly related to the Hammett substituent constants. No such relationship exists for the ortho-substituted compounds. The magnitude of the chemical shift is independent of substrate concentration over a five-fold variation.
