The Triplet State and Molecular Electronic Processes in Organic Molecules

摘要: The first identification of a spectroscopic phenome-non with the triplet level of an organic molecule was made in 1937 by Sklar (366), who observed a weak ab-sorption system in the 3400-A region of benzene and assigned it to a singlet-triplet intercombination on the basis of its feeble intensity. Prior to this, Jabtonski (170) had suggested an energy-level scheme to explain phosphorescence, a phenomenon that had been extensively studied by Vavilov and Levshin (396), Kowal-ski (203a), and others. Phosphorescence was presumed to represent …
