An Infrared Study of Carbon Monoxide Adsorbed on Platinum Electrode Modified with Bismuth Submonolayer

Infrared spectra of CO adsorbed on Pt electrodes modified with underpotentially deposited Bi adatoms have been measured in situ as a function of Bi coverage (θBi). Shape and position of the C–O stretching band changed depending upon θBi. The observed spectral changes are explained by dipole coupling between CO molecules. Structure of Bi adlayer is discussed from the spectra of CO.
