摘要：

Carbon monoxide (CO) migration on Pt(100) and Pt(11 1 1) single crystal electrode surfaces in an acid solution was studied by electrode potential modulated infrared reflection-absorption spectroscopy and time resolved infrared reflection-absorption spectroscopy. The interconversion of CO adsorbed on both electrode surfaces between on-top, asymmetric and symmetric bridge-bonded sites was caused by the applied electrode potentials. Unstable CO intermediate species were created during the interconversion of their sites.
