The adsorption of propene and 2-butenal on the Pt(1 1 1) surface has been s
tudied by high resolution photoelectron spectroscopy, both in the mono-and
multi-layer regime. The results obtained indicate an involvement of both al
iphatic and carbonyl groups in the bonding of 2-butenal with the platinum s
urface in the sub-monolayer regime. (C) 2001 Elsevier Science B.V. All righ
