We have carried out quantum‐mechanical studies of infrared multiphoton excitation and dissociation of diatomic molecules modeled by Morse oscillators. Two different aspects of such processes are investigated: one concerns quantum dynamics near a nonlinear resonance induced by an external field and calculations of the associated quasienergies and quasi‐eigen functions; and the other addresses the effects of dipole moment functions on the above‐threshold dissociation spectra, obtained by solving the time‐dependent Schrödinger equation directly using the momentum‐space Fourier–Grid method. © 1994 John Wiley & Sons, Inc.
