## Abstract The rotational barriers in sulphines containing the substituents 2,6βdimethylβ3βisopropylβ4βmethoxyphenyl and 4,6βdimethylβ3βisopropylβ2βmethoxyphenyl are discussed. Particular attention is given to the occurrence of a barrier to rotation about the isopropyl to aryl bond. In both types
## Abstract Activation parameters for the hindered rotation in some dimethylamino substituted azoles are reported and the effects of various ring systems and substituents on the barrier are discussed. Possible errors in Ξ__H__β and Ξ__S__β are investigated.
