WebOptical Activity. The stereochemistry of molecules has its roots in the work of the nineteenth‐century French physicist Jean Biot. Biot was studying the nature of plane‐polarized light (Figure 1 ) when he discovered that solutions of some organic compounds caused polarized light to rotate. Compounds with this property are called … 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 generally in chemistry to measure the concentration or enantiomeric ratio of chiral molecules in solution.
