| Abstract: | The activation parameters of internal conversion, intersystem crossing, and dissociation into radical ions were determined for the exciplexes of 9-cyanophenanthrene with 1,3,5- and 1,2,3-trimethoxybenzene. The activation enthalpies for the different processes of exciplex decay were found to be close for a given exciplex in a given solvent, thus allowing a linear approximation for the temperature dependence of the logarithm of the exciplex lifetime.Translated from Khimiya Vysokikh Energii, Vol. 39, No. 1, 2005, pp. 26–31.Original Russian Text Copyright © 2005 by Dogadkin, Dolotova, Soboleva, Kuzmin, Plyusnin, Pozdnyakov, Grivin. |
