Yates, Jr, J T

The paper summarizes the highlights of the last 3 years of work. The accomplishments described are: Development of Fourier transform infrared reflection absorption spectroscopy (FT-IRAS) for surface measurements; Improved data acquisition and smoothing methods for high resolution electron energy loss spectroscopy (HREELS); IRAS studies of the chemisorption of CO on Ni(111); Interactions between CO and K on Ni(111) as studied by laser induced thermal desorption (LITD); Direct observation of repulsive interactions between chemisorbed CO and S or Se on Pt(111); Role of surface defects in chemisorption and catalysis; Studies of a catalytic reaction on Pt(112); Activation of methane on transition metal surfaces; Dynamical studies of adsorbed CH{sub 3}O on Al{sub 2}O{sub 3}; Modification of Rh/Al{sub 2}O{sub 3} catalysts by functionalization of isolated hydroxyl groups; and C-H bond liability in adsorbed hydrocarbon layers as measured by IR spectroscopy. 28 figs.
