WebOptical Rotation of Chiral Materials Optical rotation (also referred as optical activity) is the rotation of the plane of polarization of linearly polarized light as it travels through certain … The term optical activity is derived from the interaction of chiral materials with polarized light. In a solution, the (−)-form, or levorotatory form, of an optical isomer rotates the plane of a beam of linearly polarized light counterclockwise. The (+)-form, or dextrorotatory form, of an optical isomer does the opposite. The rotation of light is measured using a polarimeter and is expressed as the optical rotation.
