Abstract

A theory for intrinsic magnetic shielding non-equivalence of the geminal nucleiUa and Ub in ethanes CXYZ-CUaUbV and but-2-ynes CXYZ-CC-CUaUbV is developed and illustrated with the aid of symmetry auguments and mechanistic models. Special attention is given to mechanisms which survive when internal rotation is free and to the attenuation of intrinsic anisochrony with increasing separation between the chiral perturbing group and the sensor nuclei.
