Definitions for optical rotation
This page provides all possible meanings and translations of the word optical rotation
Random House Webster's College Dictionary
the angle at which the plane of polarized light is rotated when passed through an optically active substance.
Origin of optical rotation:
The rotation of the plane of polarization of plane polarized light as it passes through a chiral medium
Optical rotation is the turning of the plane of linearly polarized light about the direction of motion as the light travels through certain materials. It occurs in solutions of chiral molecules such as sucrose, solids with rotated crystal planes such as quartz, and spin-polarized gases of atoms or molecules. It is used in the sugar industry to measure syrup concentration, in optics to manipulate polarization, in chemistry to characterize substances in solution, and in optical mineralogy to help identify certain minerals in thin sections. It is being developed as a method to measure blood sugar concentration in diabetic people.
U.S. National Library of Medicine
The rotation of linearly polarized light as it passes through various media.
