WebApr 29, 2024 · The RS system assigns a priority sequence to the groups attached to the chirality center and, tracing a curved arrow from the highest priority group to the lowest, labels each chiral center R or S. First rule A priority sequence is assigned to the groups based on the atomic number of the atoms directly attached to the chiral center. WebMay 14, 2016 · L and D refers to the direction of rotation of plane-polarized light. R and S refer to the absolute configuration possessed by the chiral centre. L short for "laevorotatory" and D "(dextrorotatory)" refer to the direction, anticlockwise, or clockwise, that a solution of the molecule rotates plane-polarized light. It is a bit of an old-fashioned term, but it …
