Abstract

AbstractAnalysis of single resonance 13C‐FT NMR spectra has yielded the vicinal 13C‐1H coupling constants in monosubstituted propanes for substituents from the first row of the Periodic Table. Directly bonded 13C‐1H, vicinal 1H‐1H and some directly bonded 13C‐13C coupling constants are also reported. The influence that the substituent electronegativity of the elements from the first row of the Periodic Table exerts on the vicinal 13C‐1H coupling constant is discussed qualitatively in terms of molecular orbital theory. The effects of substituents from the first row are compared with the effects of halogen substituents.
