circular+dichroism

Circular dichroism — (CD) refers to the differential absorption of left and right circularly polarized light.[1][2] This phenomenon was discovered by Jean Baptiste Biot, Augustin Fresnel, and Aimé Cotton in the first half of the 19th century.[3] It is exhibited in… …   Wikipedia
