Abstract

Consideration of the non equivalence of hydrogen atoms in a methyl group attached to a planar moiety indicates that a component of electric dipole moment should exist in a direction perpendicular to the local C3 axis of the CH3 group. Semiempirical molecular-orbital computations produced estimates of this moment and of the barriers to internal rotation which may make this moment observable.

Key words
