Abstract
Ramped field desorption has been employed to probe the binding states of adsorbed species. The use of fast linear ramps with slopes of 107·V/m ns allows us to combine this method with time-of-flight mass spectrometry. First results are presented for the desorption of NO adsorbed at step sites of Pt field emitter tips. We describe the general formalism for calculating the field desorption rates. The application to the system NO/Pt yields considerable agreement between theory and experiment.
