Infrared laser-induced photodesorption of physisorbed NH3 from Cu(100) single crystal is achieved via resonant pulsed CO2 laser excitation of the symmetric deformation mode δ3 and-detected by time-of-flight mass spectrometry. Photofragmentation and photoionization at increased laser intensities are also observed.
