Quantum Vibrational Motion in Polyatomic Molecules from Femtoseconds to Days
We provide a brief review of the work from the Zürich group on the primary processes of molecular motion and kinetics during and after excitation of vibrational motion by intense coherent infrared radiation. Very short (fs and below) and very long (Ms) time scales are considered. We emphasize the fundamental concepts and provide a comparative discussion of the “direct” kinetic approach, say, by time resolved pump-probe spectroscopy and the “indirect” spectroscopic approach, emphasized in our work. Some recent results on wavepacket motion in functional groups of polyatomic molecules are mentioned and a list of key references is provided.
