We report scattering experiments of multiphoton vibrationally excited SF6 molecules from graphite surfaces demonstrating ro-vibrational excitation in the collision. The beam scattering experiments were carried out at different initial kinematic conditions and as a function of the surface temperature. The energy transfer depends both on the initial state of the molecule and on the momentum transferred as well as on the temperature of the surface. The role of surface atomic corrugation is evidenced.

Abstract
We report scattering experiments of multiphoton vibrationally excited SF6 molecules from graphite surfaces demonstrating ro-vibrational excitation in the collision. The beam scattering experiments were carried out at different initial kinematic conditions and as a function of the surface temperature. The energy transfer depends both on the initial state of the molecule and on the momentum transferred as well as on the temperature of the surface. The role of surface atomic corrugation is evidenced.File in questo prodotto:
