Circular dichroism (CD) finds widespread application as an optical probe for the structure of molecules and supramolecular assemblies. Its underlying chiral light-matter interactions effectively couple between photonic spin states select quantum-mechanical degrees freedom in a sample, implying intricate connection with photon-to-matter quantum transduction. However, effective transduction implementations likely require that are antisymmetric respect to direction light propagation through yielding inversion chiroptical response upon sample flipping, which is uncommon CD. Recent experiments on organic thin films have demonstrated such behavior, was attributed "apparent CD" resulting from interference sample's linear birefringence dichroism. theory connecting selection rules microscopic electronic constituent remains be formulated.
