A method is developed to determine the parameters of electromagnetic and elastic excitations in molecular crystals including the polariton resonance region. The dependence of eigenvectors and eigenfrequencies on the wavevector of elementary excitations is calculated numerically for m‐chloronitrobenzene crystals. The conditions are found when the photon‐phonon resonance effect becomes observable in the Raman scattering (RS) spectra of this crystal.
