Dichroism wikipedia
Websi.wikipedia.org WebThe differential absorption of radiation polarized in two directions as function of frequency is called dichroism. When applied to plane polarized light, this is called linear dichroism; for circularly polarized light, circular dichroism. We can think of linear polarized light as the result of two equal amplitudes of opposite circular polarization.

Left-hand circular (LHC) and right-hand circular (RHC) polarized light represent two possible spin angular momentum states for a photon, and so circular dichroism is also referred to as dichroism for spin angular momentum.
