    • At low oxygen coverages, hydrogenation of the adsorbed alkyl species was also observed due to reaction with surface hydrogen produced (in part) by hydrogen elimination reactions.

    • The difference in the gas-phase C-X bond strengths of 2-propyl iodide and thiol of ∼16 kcal/mol agrees well with the ∼12 kcal/ mol difference in activation energies for reaction of the two molecules on Rh(111)-p(2×1)-O, estimated by a leading-edge analysis of the respective temperature programmed reaction traces, lending additional credibility to the proposed radical I mechanism.

    • Although higher resolution is possible for atoms or diatomics bound to metal surfaces, larger molecules condense on the electron optics and degrade the spectrometer resolution.

    • 3v symmetry refers to the adsorbate. Our experimental observations indicate that the methyl stretch and deformation modes are not sensitive to the symmetry of the surface.

    • note
    • This discrepancy is not due to mechanical renormalization effects, which result from the additional mass associated with the extended surface, since that would give rise to an increase in the observed frequency.
