JASCO J-815 Spectropolarimeter
Circular dichroism is a phenomenon based on the differences in the absorption of right- and left-circularly polarized light by a substance. Left- and right-circularly polarized light represent two possible states of photon momentum, which is why circular dichroism is also called spin angular momentum dichroism. Circular dichroism is a manifestation of optical activity. It manifests itself in the absorption bands of optically active chiral molecules.
