摘要：

Proton magnetic resonance spectra of several mono‐ and disubstituted benzaldehydes were studied using CW, INDOR and double resonance techniques. It was verified that substitution in the para position has no effect on the long‐range coupling of the aldehydic proton with the ring protons five bonds away. Substitution in the ortho and meta positions (with the exception of 2,4‐dinitrobenzaldehyde) follows closely the additivity rule effects of the substituents. Copyright © 1979 Heyden & Son Ltd.
