<Stephen F. Mason> investigated <optical activity> and molecular dissymmetry in coordination chemistry. His account distinguishes different refractive indices for opposite circular polarizations from unequal absorption of those polarizations.
The first produces circular birefringence and the second <circular dichroism>. They probe related aspects of a chiral material through different experimental observables.<Optical Activity and Molecular Dissymmetry in Coordination Chemistry by Stephen F. Mason>[Printed pages 335–336, Introduction]{ref}
A <chemist> who studied <optical activity>.
