Abstract: The phonon sidebands associated with the phosphorescence of naphthalene in p-dibromobenzene and $\alpha$-phase p-dichlorobenzene seem to exhibit some degree of localization, while the phonon sideband of the phosphorescence of naphthalene in $\gamma$-phase p-dichlorobenzene seems to be entirely delocalized. A correlation is suggested between the degree of localization and the strength of the excitation-phonon coupling as measured by the optical Debye-Waller factor. It is further shown that the strength of coupling of the phonons to the electronic transition is independent of the gas-to-crystal shift of the impurity.
