Vicinal carbon‐proton spin‐spin coupling constants in monosubstituted propanes

This is the authors' abstract. We don't add key points for this paper.

Analysis of single resonance 13 C‐FT NMR spectra has yielded the vicinal 13 C‐ 1 H coupling constants in monosubstituted propanes for substituents from the first row of the Periodic Table. Directly bonded 13 C‐ 1 H, vicinal 1 H‐ 1 H and some directly bonded 13 C‐ 13 C 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 13 C‐ 1 H 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.
