## Abstract Carbon‐13 chemical shifts and ^13^C−^15^N 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 th

## Abstract Carbon‐13, proton coupling constants have been measured in eighteen different 2‐substituted propanes. ^1^__J__(C‐2,H) shows variations similar to those observed previously for monosubstituted methanes. ^2^__J__(C‐2,H) is essentially independent of the substituent at C‐2, while ^2^__J__(

## Abstract Carbon–proton and carbon–deuteron coupling constants were measured in the isotopomers CH~2~Cl~2~, CHDCl~2~ and CD~2~Cl~2~. The primary and secondary isotope effects on the carbon–proton coupling are −0.60 (±0.05) and −0.25 (±0.01) Hz, respectively. The deuterium‐induced ^13^C isotope sh
