“…Low-energy electron bombardment may be used to break bonds in adsorbed molecules. ,− In the particular case of cyclopropane on Cu(111) and Cu(110) surfaces, a dissociative electron attachment (DA) resonance is detected at approximately 10 eV . HREELS data demonstrating DA dissociation of cyclopropane at 90 K on Cu(111) are presented in Figure .…”

“…Surface science studies of the interaction of cyclopropane with clean single-crystal metal surfaces have been reported for Ru(0001), Ru(112̄0), Ni(100), Pt(111), Cu(110), Cu(111), Ir(111), ,, and the reconstructed Ir(110)-(1 × 2) surface. ,, Cyclopropane dissociates on the latter surface below 100 K, but desorbs molecularly from the remaining surfaces in the 125−150 K range. The present HREELS (high-resolution electron energy loss spectroscopy) and TPD (temperature-programmed desorption) study shows that cyclopropane desorbs molecularly from Cu(111) and Cu(110) at 125 K. Hence, adsorption of cyclopropane onto these surfaces in a UHV (ultrahigh vacuum) experiment is not a feasible method for preparing adsorbed species such as 1 − 4 .…”
