Optical active compounds
WebOptical rotation, also known as polarization rotation or circular birefringence, is the rotation of the orientation of the plane of polarization about the optical axis of linearly polarized light as it travels through certain materials. Circular birefringence and circular dichroism are the manifestations of optical activity.

WebJan 13, 2024 · Specific rotation is characteristic value for every optically active compound. Observed rotation of a compound may vary as per variation in concentration and length of the sample tube, but the specific rotation is a constant value for every optically active compound. Following is a formula used for calculation of specific rotation: 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 …
