Executive Summary : | Inelastic scattering of gas molecules on surfaces is a fundamental process that has been investigated extensively. This process involves the exchange of energy between the gas molecule and the surface, resulting in energy redistribution among the internal and translational degrees of freedom of the scattered gas molecules. However, the mechanism of energy transfer between the molecule and surface is quite complicated and still not well understood. In particular, the study of the scattering of polyatomics from surfaces is more challenging due to the complexity that arises from the increase in the number of degrees of freedom. In the proposed study, the inelastic scattering of gas molecules such as NH₃, CO₂, NO₂, methylformate, and nitromethane from different solid surfaces such as Au, single-layer graphene, graphite, siO₂, TiO₂, and LiF will be investigated by computer simulations. The results of the simulations will be compared to the observations from molecular beam experiments. |
