shown that the geminal anisochronism is a consequence of the molecular chirality arising from slow rotation of the aryl ring with respect to the thioamide group. The free-energy barrier to this process has been found to lie in the range 11.2–13.4 kcal mol–1, increasing with the size of the N-alkyl groups. A lower energy process (ΔG‡= 8.6 kcal mol–1) in 2-hydroxy-NN-di-isobutylthiobenzamide has been
