Abstract

Thermal desorption of molecules from surfaces provides a unique opportunity to relate kinetic measurements to equilibrium properties. The transition state can frequently be quantitatively characterized, and dynamical effects can be independently assessed via the sticking probability. Thus desorption rates reflect directly thermodynamic properties of the adsorbate-substrate system. Competition among product channels, energy and angular requirements for adsorption, effects of steps or defects, mobility, and orientational constraints on adsorbates can all be understood with this framework. Significant deviations from Arrhenius behavior may result from incomplete energy equilibration, coverage dependent configurational entropy, or most strikingly, from phase transitions involving the adsorbate layer.
