We have determined the band structure for the surface-localized states on a clean and hydrogen-covered Rh(111) surface using angle-resolved photoemission. Several of our observed bands are strikingly similar to those observed previously on Pt(111) if the Fermi level is shifted appropriately given the fewer valence electrons in rhodium. A deviation from this rigid-band behavior is observed for surface bands in the vicinity of the Fermi level near the [ital [bar K]] point of the surface Brillouin zone. We also compare our results to existing calculations. We find that these generally provide a good match to our results, although more surface bands are observed than calculated.
