State-To-State Thermal/Hyperthermal Collision Dynamics of Atmospheric Species

Abstract

Direct absorption IR laser methods developed under AFOSR support have been study state-to-state reactive scattering dynamics in collisions systems under crossed supersonic jet, single collision conditions. Time resolved flash kinetic studies of the OH/HO2/O3 chemical chain reaction has been performed from 300K down to 190K, providing first access to temperature conditions relevant to accurate modeling of the lower stratosphere. Most recently, these methods have been extended to study "airglow" dynamics of highly rotationally excited OH(v,N) radicals formed from H+O3 reactions.
