Abstract

Laser-induced desorption, dissociation and ionization of dimethylcadmium (DMCd) molecules adsorbed on various substrates have been studied using laser desorption mass spectrometry. These processes are controlled by resonant multiphoton absorption of UV radiation in adsorbate as well as photoelectronic or thermal excitation of substrates. Resonance-enhanced processes in DMCd physisorbed multilayers initiated by KrF laser have been examined. Attempts to realize a purely thermal desorption of this adsorbate due to heating of various substrates by lasers on XeCl, YAG:Nd³⁺, and CO₂ have been undertaken.
