摘要：

We designed an ultrahigh vacuum high-pressure (UHVHP) reaction system for in situ sum frequency generation studies. This system allows for pressure (10(-9) Torr-1 atm), and temperature (150-1100 K) dependent investigation of adsorbates on single crystals or polycrystalline foils and of catalytic reactions. By combining two optical parametric systems, we are able to simultaneously detect CO and ethylene on Pt(111) surface. A gas chromatograph is used to monitor the kinetics of ethylene hydrogenation on Pt(111). (C) 2001 American Institute of Physics.
