Abstract
The transport properties of a composite exciton-phonon (CEP) is presented by calculating the rate of its trapping at impurities by emitting a phonon. It is demonstrated for the first time that a Debye-Waller type factor reduces the trapping probability in molecular crystals in the same way as that does in the electronic transport processes in atomic crystals.
