Long-range ordered acetate structure on Cu(110)

A chemisorbed layer prepared by exposing a clean Cu(110) surface to acetic acid, CH 3COOH, at room temperature was studied by LEED and X-ray photoelectron diffraction (XPD). LEED shows a well ordered pattern with an oblique 4 −4 1 1 unit cell. The equivalent oxygen coverage is 0.75 corresponding to...

Description
Summary:A chemisorbed layer prepared by exposing a clean Cu(110) surface to acetic acid, CH 3COOH, at room temperature was studied by LEED and X-ray photoelectron diffraction (XPD). LEED shows a well ordered pattern with an oblique 4 −4 1 1 unit cell. The equivalent oxygen coverage is 0.75 corresponding to three acetate species per unit cell. Polar angle O 1s and C 1s intensity distributions measured in four different azimuths for this layer show a large number of peaks which can be correlated with an ordered array of acetate species of two different configurations. A structure model for the acetate layer is proposed on the basis of LEED and XPD data. Single scattering model calculations carried out for this model show good agreement with experiment.
