Reliable, with one-point correction of energy scale
Comment:
CCH3/Pt(111)(2x2). The coverage was 0.25. Peak location: Voigt function. CCH3 was formed by annealing the C2H4 covered Pt surface to 370 K. The Pt(111) crystal was cleaned by cycles of Ar+ ion bombardment and annealing. The spectra were recorded at normal emission.
