✦ Synopsis
An electronic transition that has both dipoiar and quadrupolar character will have a different probability of excitation when induced by circularly polarized light of opposite sense, depending on the orientation of every individual chromophore being excited relative to the light beam. if brownian motion is frozen during the lifetime of the excited state, the excited population of molecules photoselected by circularly polarized li_ght of a given sense will emit partially circularly polarized tight, the extent of which depends on the molecular spect;oscopic parameters.
