✦ Synopsis
Alternate surface reaction channels involving CO dissociation and the inhibition of dissociation on Mo( 110) have been detected directly by vibrational studies using EELS. The CO species that exhibit au (CO ) of 1345 cm-' can be converted completely to adsorbed atomic carbon and atomic oxygen via an intermediate with u( CO) = 1130 cm-'. Alternatively, when oxygen is chemisorbed with the CO species that exhibit a v(C0) of 1345 cm-', CO dissociation is inhibited, and the CO is converted to CO species with v(C0) = 2000 cm-' viaan intermediate species with v(C0) of 1465-1535 cm-'.
