## Abstract The magnitude of the NMR spinβspin coupling constant, ^3^__J__(CH), between a vicinal ^13^Cβ^1^H pair depends, __inter alia__, on the value of the torsion angle Ξ¦~CH~(^13^Cο£ΏCο£ΏCο£ΏH) and is influenced by the presence of an electronegative substituent located on the coupling ^13^C nucleus.
