Abstract

Nanosecond laser-induced photoreactions of (NO)(2) adsorbed on Ag(111) at 75 K are investigated by mass-selected photoinduced desorption (PID) and time-of-flight (TOF) measurements. It has been found that N(2) as well as N(2)O is formed by a photoinduced abstraction reaction within a single (NO)(2). The photoproduct N(2) desorbs with a very high translational temperature (5700 K) as a result of strong repulsion by the surface upon its formation. The Ag surface shortens the N-N bond of (NO)(2) to enable N(2)O and N(2) formation.
