Energy Transfer Dynamics in Isolated and in Colliding Highly Vibrationally Excited Molecules
Abstract
Our program explores the nature of highly vibrationally excited molecules and discovers the details of their intramolecular dynamics, both for colliding and isolated molecules. We use the combination of laser preparation of a rovibrational eigenstate and laser induced fluorescence probing of the vibrationally excited molecule to identify and characterize the initially excited vibrational state determine the state to state relaxation pathways and rates of the vibrationally excited molecules, and characterize of the excited electronic state in the probe step. We prepare an initial state by exciting a vibrational overtone transition with a pulsed laser and interrogate the highly vibrationally excited molecule, either immediately after excitation or after a time delay, with a second ultraviolet laser. The excitation transition reaches a high vibrational level in the ground electronic state, and the probe transition is to an electronically excited state from which we observe fluorescence.
