In the ARUP spectra for CO adsorbed on the K/Ru(1010) surface two peaks are observed respectively at 7.8 eV and 11.2eV binding energies. The peak 11.2 eV BE represents the CO-4a1 (5σ), which is forbidden under s-polarized light. According to the selection rule, the result supports the sp2-rehybridized model under the strong influence of coadsorbed K atoms on Ru(1010) surface and shows the CO bridge adsorption at 〈1210〉 azimuth.
- CO orbital,
- Polarized light UPS,
- sp²-rehybridized model
