WebIn chemistry of an optically active compound or crystal terms the difference between levorotatory and dextrorotatory is that levorotatory is that rotates the plane of polarized light to the left, or anticlockwise while dextrorotatory is that rotates the plane of polarized light to the right, or clockwise. WebApr 28, 2024 · It thus has greater generality than the D/L system, and can label, for example, an (R,R) isomer versus an (R,S) — diastereomers. The R/S system has no fixed relation to the (+)/(-) system. An R isomer can be either dextrorotatory or levorotatory, depending on its exact ligands. The R/S system also has no fixed relation to the D/L system.
