Abstract

There is growing interest in identifying transient structures, mode-specific energy content and reaction products generated in condensed-phase molecular systems on the picosecond or shorter timescale. This information is important for understanding the details of chemical reaction mechanisms and kinetics at ambient or elevated temperatures, especially for polyatomic molecules in solution. Recent developments in the field of ultrafast time-resolved infrared (IR) spectroscopy show promise of being able to observe these dynamical processes. In this poster, transient IR spectral measurements for CO-stretching vibrations of metal-carbonyl molecules and cluster compounds in solution which identify vibrational relaxation rates, intra-mode and intermolecular energy transfer and photo-dissociation products will be presented.
