| Abstract: | By means of high-resolution electron energy loss spectroscopy the surface intermedaites formed during the interaction of methane and chemisorbed oxygen on Ni(100) were examined. For oxygen adlayers of less than monolayer, as monitored by LEED, the formation of a surface species with an EELS vibration of 1725 cm-1 was observed at 200 K. Assignment of this frequency to a surface intermediate is discussed. |
