Abstract: For pt.I see ibid., vol.11, p.1283 (1978). Using the Green function obtained in pt.I, the author obtains explicit expression for the two-phonon absorption coefficient of internal modes of molecular crystals. This expression is compared with the IR transmission spectra of CO 2 , N 2 O and OCS crystals and excellent agreement is found, in terms of two-phonon bound-states and resonances, for both shape and intensity of the bands under consideration.
