A simple model of optical detrapping in molecular crystals is proposed. It includes the coupling of electronic and vibrational degrees of freedom, due to the displacement of the equilibrium position in intramolecular vibrations upon ionization or electronic excitation of the molecule. The coupling is shown to shift the apparent distribution of trap depths towards greater values. Possible relevance of the model to the interpretation of experimental data is discussed and new experiments are suggested.
