摘要：

An ultrahigh vacuum chamber equipped with Fourier transform reflection absorption infrared spectroscopy, Fourier transform mass spectrometry, laser-induced thermal desorption, Auger electron spectroscopy, and low energy electron diffraction is described. The marriage of the various techniques has]ed to novel designs for sample manipulation and incorporation of the instrumentation. A new ion deflection technique is also described. Some results from studies of hydrocarbon reactions on Pd(111) surfaces, such as desorption kinetics for propene and the kinetics and mechanisms of acetylene cyclization to benzene and thiophene, are discussed, as are analyses of oxidized Ti foils exposed to the ambient environment. The performance of this instrument is thus evaluated. (C) 1997 American Institute of Physics.
