ON THE ORIENTATION OF LOW-TEMPERATURE PI-BONDED ETHYLENE ON PT(111)

[摘要] The adsorption of ethylene on Pt(111) has been followed, using UPS and detection at the normal and off-normal, at temperatures low enough to allow multilayer growth. The absence of an orbital, at the normal, during the first stages of adsorption and its presence from the beginning, off-normal, allowed us to conclude that the first (pi-bonded) monolayer is oriented flat and parallel to the surface.
