## Abstract A new theory of the vibronic absorption spectra of molecular crystals, which is a generalization of the usual exciton theory, is suggested. It allows to consider, in principle, both oneβphonon and manyβphonon vibronic excitations. An investigation of the vibronic states corresponding to

## Abstract An investigation is made of the vibronic spectra of molecular crystals for the case of a combination of the electronic excitation with the nonβtotally symmetrical intramolecular vibration. It is shown that, depending on the crystal characteristics determining the values of the theoretic
