Abstract
PHOSPHORESCENCE in homogeneous rigid media was identified by Lewis, Kasha and Calvin1 during 1941–45 as triplet→singlet emission spectra. Simultaneously Weisman and Lipkin2 were able to show by a wide-angle interference technique that these emissions are electric dipole transitions. Following these investigations, selection rules for triplet–singlet transitions, based on the triplet states undergoing spinorbit coupling due to the spin magnetic moment of the electrons interacting with the molecular field, were given by McClure3 and placed on a rigorous basis by Weisman4. Recently, Hutchison and Mangum5, by observing paramagnetic resonance absorption in the phosphorescent state of naphthalene, have confirmed the triplet assignment.
