Abstract:

An ab initio quantum-chemical calculation of the direct 13 C- 1 H spin-spin coupling constants in the CH 4 -H 2 O system was carried out and experimental data obtained for a series of N-vinyl compounds were analyzed. The specific C-H...X (X = O, N) intramolecular interactions result in increasing the direct 13 C- 1 H spin-spin coupling constant of the hydrogen involved in bonding and decreasing the direct 13 C- 1 H spin-spin coupling constant for the hydrogen atom that takes no part in the interaction.
