# COHERENT NUCLEAR MOTION IN A CONDENSED-PHASE ENVIRONMENT : WAVE-PACKET APPROACH AND PUMP-PROBE SPECTROSCOPY

@article{Muhlbacher1999COHERENTNM, title={COHERENT NUCLEAR MOTION IN A CONDENSED-PHASE ENVIRONMENT : WAVE-PACKET APPROACH AND PUMP-PROBE SPECTROSCOPY}, author={Lothar Muhlbacher and Andreas Lucke and Reinhold Egger}, journal={Journal of Chemical Physics}, year={1999}, volume={110}, pages={5851-5860} }

A quantum-mechanical Gaussian wave-packet approach to the theoretical description of nuclear motions in a condensed-phase environment is developed. General expressions for the time-dependent reduced density matrix are given for a harmonic potential surface, and the exact quantum dynamics is found for a microscopic system-plus-bath model. Particular attention is devoted to the influence of initial correlations between system and bath for the outcome of a pump–probe experiment. We show that the…
