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 referred to as dichroism for spin angular momentum. This phenomenon was discovered by Jean-Baptiste Biot, Augustin Fresnel, and Aimé Cotton in the first half of the 19th century. Circula… Webbirefringence and dichroism can also be observed in extrin-sically chiral systems. In such a system a non-chiral struc-ture together with the incident wave forms a geometrical arrangement that cannot be superimposed with its mirror im-age and thus the whole arrangement is chiral.
