Optical Activity Observed rotation The number of degrees, , through which a compound rotates the plane of polarized light. Weboptical activity, the ability of a substance to rotate the plane of polarization of a beam of light that is passed through it. (In plane-polarized light, the vibrations of the electric field are confined to a single plane.) The intensity of optical activity is expressed in terms of a quantity, called specific rotation, defined by an equation that relates the angle through …
WebOptical activity is a macroscopic property of a collection of these molecules that arises from the way they interact with light. Compounds, such as CHFClBr, that contain a single stereocenter are the simplest to understand. One enantiomer of these chiral compounds is dextrorotatory; the other is levorotatory.
