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 Schrodinger equation directly using the momentum-space Fourier-Grid method.

A vectorizable FORTRAN code for the ETA10 or other vector machines for numerical calculation of the time-dependent Schrodinger equation is presented. Preliminary results for the multiphoton dissociation of nitrogen oxide are shown. The applied electric field was approximated by a classical sinusoidal wave; both sinusoidal and cosinusoidal wave forms were tested, and the internuclear potential was taken to be a Morse function. Dissociation histories of three types were found.
