Photoemission indicated that the surface resonances on Mo(100) were not removed entirely by the adsorption of H2. It also showed two H-induced states below the bulk d-band edge with the binding energies independent of coverage and in good agreement with a calculation. The results indicate that H on Mo(100) was bridge bonded with the local bonding configuration relatively unchanged by reconstruction. A significant correlation between the surface resonances and the surface reconstruction was suggested.
