A principle describing the effect of exciton bandwidths on the intensity of phonon sidebands in electronic spectra of molecular crystals is derived from some experimental observations, from some simple arguments, and from l &e quantum theory of electron-phonon coupling.
An experimental method involving the temperature dependence of the intensity of trap emission is employed to determine the sign and magnitude of the nearest-neighbor intermolecular interaction matrix element responsible for triplet exciton transport and the number of wave vector states comprising th
The pulse recovery method is applied to the triplet states of naphthalene, quinoxalene, and tetramethylpyrazine 03iP) in durene and biphenyi host crystals for 1.25% d Td 4.23%. Temperature dependen~es of the spin-lattice relaxation rates are characteristic of Raman and direct processes.
