The end-on and tilted type species of adsorbed ethene were observed on clean Cu (110) surface at 110K.

The π-adsorption took place on oxygenmodified Cu (110) surface, where the oxygen induced (2×1) reconstructed phase was formed. It was suggested that the surface structure was more essential for orientation of the π-adsorbed ethene than the long range effect. The heat of adsorption of π-bonded ethene on the (2×1)-O/Cu (110) surface was estimated to be 32±7 kJ/mol from the analysis of the adsorption isobar obtained by IRAS.
