Abstract
Optical rotation for random molecular systems is proportional to the second-order matrix element over the pseudoscalar operator $\mu.m$. For inherently active molecules in non-degenerate ground states with charge density belonging to the totally symmetric irreducible representation, the pseudoscalar must also belong to this same representation. The present work will discuss the effect of degenerate ground as well as intermediate states. Possible matrix elements and symmetries involving various components of the degenerate set will be deduced using the irreducible tensor coupling $coefficients.^{1}$ The physical implication of these degeneracies will be discussed. $^{1}$ J.
