Abstract Theoretical and experimental investigations of resonance hybridization between impurity and local states are carried out in naphthalene with benzselenophene impurities. The analysis of the vibron regions of the luminescence and absorption spectra of this system shows that the hybridization effect really takes part in such a system and there are two centres with impurities being in non‐equivalent positions. Moreover each impurity perturbs two molecules of the crystal. The matrix elements of the resonance interaction between impurity and crystal molecules are given.
