Abstract
Using C Is and O Is scanned-energy mode photoelectron diffraction, the loca l adsorption site and orientation of CO adsorbed on Cu(210) has been determ ined. The results show that the molecule adsorbs in an essential on-top sit e through the C atom with C-Cu and C-O bondlengths generally consistent wit h previous studies on low index Cu surfaces. The molecule has a significant tilt (18 +/- 6 degrees) of the C-O axis away from the surface normal, with components both perpendicular and parallel to the [0 0 1] steps on this su rface.
