Time-of-Flight and Internal State Distributions of Photodesorbed Species from N2O Adsorbed on Pt(111) by 193 nm light.
Polarized ultraviolet light from an excimer laser (193 nm) was used to photodesorb and photodissociate N2O adsorbed on a cold Pt(111) surface. The desorbed species and their time-of-flight (TOF) were monitored by resonantly enhanced Multi Photon Ionization (MPI) spectroscopy of N2 and atomic oxygen. We have identified three major channels: thermal desorption of molecular N2, photodesorption of ground electronic state N2O, and ejection of ballistic oxygen atoms.
