Abstract
Ethene and propene adsorption on Ru(0001) has been studied using refle ction-absorption infrared spectroscopy (RAIRS). Low temperature (appro ximately 100 K) adsorption of ethene is presumed to produce a di-sigma adsorbed species but this was not detected. Low temperature adsorptio n of propene produced a physisorbed layer but at 130 K a weak spectrum attributed to a di-sigma adsorbed species was observed. Ethene and pr opene both converted to alkylidyne species at higher temperature and p ropylidyne decomposed via the ethylidyne species.
