Abstract
We discuss the spectrum (linewidths and positions) of the first triplet state of the molecular crystals anthracene, napthalene, and phenazine. These crystals have similar exciton bandwidths, but varying amounts of anisotropy in the intermolecular interactions. We analyze the linewidths at zero temperature using isotopic scattering as the broadening mechanism, and the temperature dependence using one and two phonon scattering processes as the broadening mechanism.Keywords
