“…It was suggested that this problem can be eliminated by building a gas doser to localize exposure pressure just on the sample surface and using differentially pumped QMS isolation aperture (shield). (85) Similar findings were observed in this study before a stainless steel shield was installed to cover the QMS probe. Another disadvantage of TPD is that it destroys adsorbed layer.…”

“…(77,85) Usually, the surface area of the sample support is larger than the sample itself and additional desorption can be observed either as a large background interference or as a separate peak in a TPD spectra. It was suggested that this problem can be eliminated by building a gas doser to localize exposure pressure just on the sample surface and using differentially pumped QMS isolation aperture (shield).…”

“…24 The hollow central part of the sample holder is made of oxygen free high conductivity copper which is silver soldered to a vertical stainless steel cryotube of 126 cm length and which can be filled with liquid N 2 for sample cooling. Two copper arms are attached to the central part with sapphire spacers (Swiss Jewel, 15.5 mm diameter, and 0.5 mm thick).…”

We report the design and characterization of a new molecular-beam/surface-science apparatus for quantum state-resolved studies of gas/surface reaction dynamics combining optical state-specific reactant preparation in a molecular beam by rapid adiabatic passage with detection of surface-bound reaction products by reflection absorption infrared spectroscopy (RAIRS). RAIRS is a non-invasive infrared spectroscopic detection technique that enables online monitoring of the buildup of reaction products on the target surface during reactant deposition by a molecular beam. The product uptake rate obtained by calibrated RAIRS detection yields the coverage dependent state-resolved reaction probability S(θ ). Furthermore, the infrared absorption spectra of the adsorbed products obtained by the RAIRS technique provide structural information, which help to identify nascent reaction products, investigate reaction pathways, and determine branching ratios for different pathways of a chemisorption reaction. Measurements of the dissociative chemisorption of methane on Pt(111) with this new apparatus are presented to illustrate the utility of RAIRS detection for highly detailed studies of chemical reactions at the gas/surface interface. © 2013 AIP Publishing LLC.

Infrared reflection-absorption spectroscopy and density functional theory, within the generalized gradient approximation, were used to investigate both experimentally and theoretically N 2 chemisorption on stepped and smooth Pt surfaces. N 2 chemisorption was observed to occur only on the edge atoms of step defect sites in atop configuration by both methods. The calculated vibrational frequency of N 2 chemisorbed on Pt͑112͒ step sites ͑2244 cm Ϫ1 ͒ is in good agreement with the frequency observed experimentally ͑2231-2234 cm Ϫ1 ͒ at saturation coverage on Pt͑335͒ and Pt͑779͒. The predicted small N 2 binding energy confirmed its weak chemisorption on Pt surfaces claimed in previous studies. The calculations indicate that N 2 decreases and CO increases the work function of the Pt͑112͒ surface. N 2 could be coadsorbed with CO below saturation coverage of the steps with CO and there is a charge transfer between the two adspecies through the substrate.
