Abstract

The influence of substrate-induced vibrational relaxation on desorption induced by electronic transitions (DIET) is studied using a density matrix formulation. The one-dimensional model describing the DIET dynamics of NO consists of two electronic states. Relaxation in both electronic and vibrational modes is simulated with dissipative Liouvillians of the Lindblad form. As expected, vibrational relaxation results in a smaller desorption yield and lower product translational temperature.
