An Analysis of the Vibrational Spectrum of Carbon Monoxide on Platinum Metal Electrodes.
Abstract
The vibrational frequencies of carbon monoxide adsorbed on a platinum metal electrode are obtained in terms of discrete interatomic interactions. We show that for linear changes in the binding energy of carbon and oxygen to the surface there is a linear dependence of the shift in CO vibrational frequency. Based on our model, we suggest that there is a direct, linear relationship between the binding energy and the applied electrostatic potential. As a result, we predict a linear dependence of the frequency on electrochemical potential in accord with experiment. We demonstrate that the application of a relatively large external electric field cannot account entirely for the observed vibrational frequency shift. We conclude that a combination of chemical bonding and electric field interactions are required to account for the observed spectral shifts.
