The peculiarities of the molecular crystal luminescence spectrum shape are considered within the framework of the polariton theory; in particular the anthracene luminescence spectrum shape caused by external phonon modes of the crystal is described. Exciton‐phonon interaction including the anisotropy of the anthracene crystal, exciton energy, and phonon modes are taken into account in the microscopic model. Determination of the radiation transmission coefficient of the crystal bordering on metallic films of various widths is performed within the framework of classical crystal optics. The results of computations of the luminescence spectra dependence on temperature, metallic film width, and crystal orientation allow to define the limits of applicability of the anthracene luminescence isotropic model. Qualitative agreement of calculated spectra with experimental data known in literature is received.
