Abstract
The molecular‐exciton Hamiltonian derived by Agranovitch {Zh. Eksp. Teor. Fiz. 37, 430 (1960) [Sov. Phys.—JETP 10, 307 (1960)]} has been diagonalized for a crystal containing a single isotopic impurity molecule. Unlike previous treatments, terms corresponding to the coupling of one‐exciton and many‐exciton states are not neglected. The results are compared with a classical theory.
