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 N2 as well as N2O is formed by a photoinduced abstraction reaction within a single (NO)2. The photoproduct N2 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 N2O and N2 formation.
