op·ti·c i·som·er·ism

stereoisomerism involving the arrangement of substituents about an asymmetric atom or atoms (usually carbon) so that there is a difference in the behavior of the various isomers with regard to the extent of their rotation of the plane of polarized light. Compare: stereoisomerism.
