WebJan 9, 2024 · O. Bertrand Ramsay. Research in Stereochemistry. In 1873, after moving to Paris to work with Charles Adolphe Wurtz, van’t Hoff realized that the phenomenon of optical activity possessed by some organic molecules—their ability to rotate plane-polarized light—could be explained by the two possible arrangements of four different substituents ... WebMay 23, 2024 · optical activity The ability of certain substances to rotate the plane of plane-polarized light as it passes through a crystal, liquid, or solution. It occurs when the molecules of the substance are asymmetric, so that they can exist in two different structural forms each being a mirror image of the other.
