Collisional Energy Transfer in Highly Vibrationally Excited Polyatomic Molecules
Abstract
The three objectives of this work are to determine the nature of highly vibrationally excited polyatomic molecule, to determine the rate constants and pathways for the collisional relaxation of these molecules, and to probe the electronic spectroscopy of these molecules. We have created and implemented approaches for accomplishing these objectives and have demonstrated their feasibility by studying the collisional energy transfer in highly vibrational excited acetylene. We have found that the collisional self relaxation rates of single angular momentum states with 10,000/cm of vibrational energy are a substantial fraction of the gas kinetic collision rates. The rate constant is about a factor of two smaller for relaxation by atomic partners. Molecular energy transfer, Vibrational energy transfer.
