Case study of 2-vinyloxypyridine: Quantitative assessment of the intramolecular CH⋯N hydrogen bond energy and its contribution to the one-bond 13C1H coupling constant

A quantitative estimate of the intramolecular CH⋯N hydrogen bond energy in 2-vinyloxypyridine and contribution to the one-bond 13C1H coupling constant from this hydrogen bond are done on the basis of experimental data and quantum chemical calculations.116
