Abstract

The vicinal ^3^J~aa~ and ^3^J~ee~ spin‐spin coupling constants of a number of deuterated trans‐1,2‐disubstituted cyclohexenes and the Δ__H__ and Δ__S__ values of the conformational equilibria of these compounds have been determined by computer optimisation of the ^3^J(HH) = f(T) function. Compounds with —CF~3~ and CCl~3~ substituents were shown to have an enhanced proportion of the diaxial conformer.
