There is this one topic and it's called optical activity. Optical Activity. Optical activity is the ability of a chiral molecule to rotate the plane of plane-polairsed light, measured using a polarimeter.A simple polarimeter consists of a light source, polarising lens, sample tube and analysing lens.
