✦ Synopsis

Recent studies in the induced circular dichroism /ICD/ allowed for generalizations referring to the mechanism of induction of optical activity in achiral species. With respect to the n-?"transition in ketones it has been shown both experimentally' and by theoretical considerations of electronic and vibrational states 2-4 that in non-associative systems: achirsl ketones /A/ -chiral solvents or solutes /C/, coupling A and C exclusively by dispersion forces produces ketone ICD which sign does not depend on relative orientations of A and C. On the other hand, different mechanism for ICD seems to operate when achiral or racemic ketones are included in Q-or &%cyclodextrin cavities 5 .
