Hydrocarbon fragments left on a Pt(111) face in the course of the thermal decomposition of unsaturated and aromatic hydrocarbons have been characterized by work function (Δφ), thermal desorption and vibrational EELS measurements. It is concluded that the different hydrocarbon parent molecules leave the same kind of electropositive CH-like species.
