✦ Synopsis

IR laser-induced desorption from benzene molecular films was studied by time-of-flight spectroscopy. Velocity distributions were measured as a function of laser wavelength, laser flucncc, film thickness and detection angle. The spectral dependence of the kinetic energy and the desorption yield follows the spectrum of the solid state, which differs considerably from the liquid state spectrum. This is consistent with a laser sublimation process. As in the case of other transient heating processes, a strong nonlinear fluence dependence of the desorption yield is observed.
