Circular dichroism (CD) is dichroism involving circularly polarized light, i.e., the differential absorption of left- and right-handed light. 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 … See more Circular polarization of light Electromagnetic radiation consists of an electric $${\displaystyle {\boldsymbol {E}}}$$ and magnetic $${\displaystyle {\boldsymbol {B}}}$$ field that oscillate perpendicular to … See more In general, this phenomenon will be exhibited in absorption bands of any optically active molecule.
