Abstract
We designed an ultrahigh vacuum high-pressure (UHVHP) reaction system for i n situ sum frequency generation studies. This system allows for pressure (1 0(-9) Torr-1 atm), and temperature (150-1100 K) dependent investigation of adsorbates on single crystals or polycrystalline foils and of catalytic rea ctions. By combining two optical parametric systems, we are able to simulta neously detect CO and ethylene on Pt(111) surface. A gas chromatograph is u sed to monitor the kinetics of ethylene hydrogenation on Pt(111). (C) 2001 American Institute of Physics.
