LASER-INDUCED THERMAL-DESORPTION OF ANILINE FROM A QUARTZ SURFACE

We present measurements of velocity and vibrational energy distributio ns of aniline desorbed from a quartz substrate by pulsed laser-induced thermal desorption. The experiments are carried out in a two laser pu mp-probe setup, using a newly developed in-vacuum dosing system for co ntinuous replenishment of the aniline layer between laser pulses. Our data indicate laser desorption of molecules at translational and vibra tional temperatures close to the equilibrium desorption temperature of aniline from quartz.
