Gaussian wavepackets in phase space, which are constructed to have the exact first and second moments with respect to the coordinates and momenta, are used to develop self-consistent equations of motion for the semiclassical time evolution of interacting anharmonic systems. The equations apply to pu

The time-dependent self-consistent field (TDSCF) approximation is applied to the coupled-mode vibrational dynamics of highly anharmonic quantum clusters, and its validity and accuracy for such systems are tested against exact quantum calculations. The calculations are pursued for bound but non-stati
