Figure 2 on p. 126102-2 was reproduced with poor resolution. A corrected version appears below.FIG. 2. STM images of Pt(110) at a CO coverage of (a) Ӎ 0.8 and (b) 1, the latter imaged in a 10 27 Torr CO background. The inset shows individual CO molecules in the ͑2 3 1͒ structure. The images are taken at 300 K as explained in the text. (c),(d) Snapshots from a Monte Carlo simulation of the surface structure at 300 K and at the same two coverages. All parameters are deduced from DFT calculations.

This study focuses on the dynamics of CO formation on Pt(111). To this end, a new semiempirical interaction potential was derived by using much of the most recent experimental information obtained from CO chemisorbed on the on top and bridge platinum sites. The dynamics on the adiabatic potential surface has been performed according to the semiclassical collisional method developed for molecule−surface interactions. The role played by the multiphonon excitation mechanism, the adsorption site, and the surface temperature effects on the Eley−Rideal recombination dynamics and on the energy fluxes through the platinum surface and the internal states of the formed CO molecules was studied in detail.
