Abstract
Resonant desorption of benzotrifluoride (BTF, C 6 H 5 CF 3 ) was accomplished by tuning CO 2 -laser radiation into the symmetric C-F-stretch vibration on the substrates NaCl(100) and C-film-NaCl(100). Time-of-flight signals of desorbed molecules are of Maxwell-Boltzmann type without additional stream velocities. Translational temperatures (up to 3000 K) are always higher than the corresponding calculate maxima of substrate surface temperature. At benzotrifluoride coverages of ≈ 60 ML, desorption yield vs laser fluence plots give a power law for resonant desorption from NaCl(100), whereas for non-resonant desorption from C-film-NaCl(100) a linear relationship is observed.
