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

Abstract

Direct absorption IR, LIF, REMPI and velocity map imaging methods developed under AFOSR support have been used to study state-to-state inelastic and reactive scattering dynamics under single collision conditions. Efforts over this past year have led to progress in multiple areas: 1) Diode laser and LIF studies of hyperthermal CO2 and NO collisions at the gasroom temperature ionic liquid (RTIL) interfaces. 2) Large scale trajectory simulations for theoretical analysis of gas-liquid scattering studies, 3) LIF data for state-resolved scattering of hyperthermal NO at the gas-molten Ga(l) interface as a function of incident energy and surface temperature, 4) Velocity map ion imaging studies elucidating state-resolved reactive scattering dynamics of HCl from self assembled monolayers (SAMs). 5) Ultrafast plasmon mediated electron ejection dynamics in single Au nanostructures via novel scanning photo-ionization imaging microscopy (SPIM) methods developed in our group.
