Abstract

Collision of a molecule with a solid surface leads to energy redistribution within its translational as well as internal degrees of freedom. The populations of the various quantum states of the latter may be probed by laser induced fluorescence (LIF) or by multiphoton ionisation (MPI). Combination of these techniques with time-of-flight (TOF) measurements in a molecular beam apparatus allows, in addition, determination of state-selected translational energy distributions.
