WebThis property is called optical activity. Left- and right-handed enantiomers turn the polarization plane in opposite directions. The angle by which the polarization plane is rotated is called optical rotation. It is measured in degrees [°OR] with a polarimeter. Chiral molecules are characterized by the mirror image constitution of their atoms. WebOptical activity is measured using a polarized source and polarimeter. This is a tool particularly used in the sugar industry to measure the sugar concentration of syrup, and …
