摘要：

Carbon‐13 chemical shifts and 13C−15N coupling constants of substituted benzaldoximes and of two non‐aromatic oximes have been determined. The coupling constants display little variation as a function of the nature or position of substitution, which suggests that perturbations in the π electron distribution have little effect. The values are compared with the markedly different ones reported for mesitaldoxime, and, in conjunction with the observed solvent effects, are discussed within the Schulman‐Venanzi framework for assessing the role of the lone‐pair.
