Abstract
The optical activity of oriented molecular systems is investigated using bianisotropic material constitutives for Maxwell's equations. It is shown that the circular birefringence and circular dichroism in a given direction can be conveniently expressed in terms of the two components of the symmetric magnetoelectric tensor of gyrotropy that are perpendicular to this direction of light propagation. This description establishes a direct link between measurable anisotropic optical activity and the tensors that describe the oscillating electric and magnetic dipole and electric quadrupole moments induced by the optical wave.
