Abstract
A theory of magnetic circularly polarized emission (MCPE) based on the formalism and methods of quantum electrodynamics is developed for luminescent molecular systems. Differential transition probabilities for the (spontaneous) emission of left- and right-circularly polarized light are calculated and these quantities are related to the observables of MCPE spectroscopy. The emission intensity variables are further related to the emission analogs of the Faraday A, B, and C parameters. The influence of photoselection and reorientational relaxation (due to rotary Brownian motion) upon the MCPE observables is also considered. Results are obtained for two excitation–emission geometries—180° (head-on) and 90° (right angle). Explicit expressions are given for the A, B, and C Faraday parameters in both the orientationally relaxed limit (isotropic emitting sample) and the photoselected, frozen limit.
