Interfacial energy exchange and reaction dynamics in collisions of gases on model organic surfaces

► Molecular beam experiments employed to study the dynamics of gas-organic surface collisions. ► Classical-trajectory simulations provided insight into gas-surface energy transfer. ► Uncovered the role of surface mass, density, and polarity in thermal accommodation efficiencies. ► Studied orientation, attractive forces, and internal energy effects in interfacial collisions. ► Elucidated the mechanism and kinetics for ozone oxidation of a model unsaturated organic surface.
