Energy Transfer and Reaction in Gas-Surface Collisions

The collision of an atom, molecule, radical, or ion with a surface may result in energy transfer and/or chemical reaction. If the interaction of this projectile with the surface is non-reactive, but still strong, the projectile may scatter off the surface with an energy distribution based on the surface temperature. QM/MM methods are under development to model gas-surface reactions. The systems under study include O(3P) + n-hexyl thiolate (SAM) and the reaction of OH with aerosols, covered by a hydrocarbon film.
