The desorption of adspecies from surfaces by laser radiation or static electric fields is an important subject for the microstructuring of materials and a challenge to theory: Not only the excitation mechanism, but also the subsequent, ultrafast dynamics in a dissipative environment, needs to be properly described. After a brief review on previous work, in this work a few new issues concerning the laser‐ or field‐induced desorption of molecules from metal surfaces [NO from Pt(111), and NH 3 from Cu(111)] will be addressed with the help of open‐system density matrix theory and wave packet propagation methods. © 2000 John Wiley & Sons, Inc.
