Energy Transfer Dynamics in Isolated and Colliding Highly Vibrationally Excited Molecules.
Abstract
The flow of energy in molecules, either isolated or colliding, is fundamental to complex phenomena occurring in atmospheric chemistry, combustion, molecular lasers, plasmas, and a host of other environments containing energetic species. We have developed, proven, and applied a technique that combines vibrational overtone excitation, to prepare highly vibrationally excited initial states, and time-resolved spectroscopic detection, to probe the evolution of the prepared state, for studying energy transfer in vibrationally energized molecules. Our experiments on acetylene have demonstrated the power of this approach for learning about otherwise inaccessible vibrations in electronically excited molecules, for determining the pathways of intramolecular energy transfer in isolated molecules, and for measuring fully state-resolved rotational and vibrational energy transfer rates in collisions. jg
