Concerning the applicability of a chirality function to different chirality observables

摘要

The applicability of a chirality function for the description of a special chiroptical property of a class of compounds does not imply its sufficiency for other observables of optical activity. Notwithstanding the fact, that molar rotations (Mλ) can be understood in terms of contributions from electronic transitions, a chirality function consistent with the optical rotations of a kind of molecules may turn out inadequate for the circular dichroism (ed). This is demonstrated by means of M and ed data of optically active 5,5′-disubstituted 2,2′-spirobiind
