“…Precedent for N 2 O acting in this manner may be found in studies demonstrating infrared resonant desorption of physisorbed N 2 O from the NaCl(100) surface. 13 This surface chemistry is not limited to the n ) 6 cluster highlighted here but is observed unambiguously for n ) 4, 6-8, almost every cluster size with appreciable signal intensity in our study.…”

“…[9][10][11] In the present investigation, we report results on desorption experiments of methane condensed on NaCl͑100͒. Experiments are performed with three methane isotopologues-CH 4 , CD 4 , and CD 3 H-as well as with mixed layers of these isotopes.…”

“…The whole macropulse, however, causes a heating of the layer by several tens of Kelvin. 22 The analysis of the TOF spectra also points to a resonant heating process. For the three isotopes the change of the flight time is found to depend on the square root of the mass as expected when desorption occurs at a definite temperature and thus with a definite kinetic energy.…”

“…Recently it has been shown that a free-electron laser ͑FEL͒ operating in the infrared is a wellsuited radiation source for this kind of investigations. [9][10][11] Theoretical studies of desorption by laser-adsorbate vibrational coupling and energy transfer have been carried out, [12][13][14][15][16][17] particularly for the well-investigated physisorption system CO / NaCl͑100͒. 18,19 In the present work the infrared laser-induced desorption of different methane isotopologues condensed on a NaCl͑100͒ single-crystal surface is investigated using the FEL of the free-electron laser for infrared experiments ͑FE-LIX͒ facility in the Netherlands as the excitation source.…”

Resonantly enhanced infrared laser-induced desorption of methane condensed on a single-crystal NaCl͑100͒ surface is observed after excitation with the widely tunable infrared laser output of the free-electron laser at the free-electron laser for infrared experiments facility using mass spectroscopic detection and time-of-flight analysis. Desorption of methane is observed only when the exciting light is in resonance with an internal vibrational mode of the molecule. Different intramolecular modes of the three methane isotopologues under study-CH 4 , CD 4 , and CD 3 H-are excited; the degenerate deformation mode 4 is observed for CH 4 and CD 4 at 7.69 and 10.11 m, respectively, as well as the 2 and 4 modes of CD 3 H at 7.79, 9.75, and 9.98 m. The desorption signals for the pure layers of these different methane isotopologues as well as for different mixtures of two of these are investigated as a function of the infrared wavelength and the laser fluence. The desorption behavior for pure and mixed layers is compared and the underlying desorption mechanism is discussed.

“…We have recently shown the feasibility of this by demonstrating the resonant infrared laser-induced desorption of N 2 O on NaCl(100) using the continuously tunable IR output of a free-electron laser. 17 Here, we will concentrate on the system CD 3 F condensed on NaCl(100) and discuss the desorption spectrum of the system, time-of-flight spectra, as well as the fluence dependence of the desorption signal.…”

In investigations of the dynamics of the desorption of molecules from surfaces, a selective excitation of specific molecular vibrations is desirable. We here report studies on the infrared laser-induced desorption of CD 3 F condensed on the NaCl(100) single crystal surface, in which the intramolecular vibrations of the CD 3 F molecules are directly excited. Desorption of the intact molecules is monitored using electron impact ionization followed by mass-selective detection in a quadrupole mass spectrometer. Desorption only occurs when the excitation laser is at 9.0, 10.5, 9.4, or 11.0 mm, corresponding to excitation on the n 2 , n 3 , n 5 , and n 6 modes of CD 3 F. An analysis of the time-of-flight spectra as a function of the laser fluence is presented. Different desorption mechanisms are discussed.
