## Abstract 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 prot
