✦ Synopsis
Based on a multi-configuration self-consistent field and a nuclear wavepacket calculation, we present the effect of dipole moments on the infrared multiphoton dissociation dynamics of hydrogen cyanide in nonstationary laser fields. Use of a linear dipole moment depresses the dissociation ability of H + CN as the laser intensity increases, compared with use of the real dipole moment function. The depression originates from the return of the nuclear wavepacket before the multiphoton dissociation. We analyze the time-dependent multiphoton dissociation yield with the dissociation yield at long time limit, dissociation rate constant and incubation time.
