WebJan 16, 2004 · The optical rotation α at a given wavelength of incident light λ is directly proportional to the difference between the refractive indices of the two circularly polarized components. The optical rotation of an optically active substance is expressed as the specific rotation [α], the molar rotation [M], and the mean residual rotation [M].
