Chirality and Optical Activity - Purdue University

WebFurther studies indicate that the rotation is caused by the chirality of the substances. The property of a compound being able to rotate the plane of polarization of plane-polarized … 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. diamond ft hawa
