โœฆ Synopsis

We report the Raman spectra of pyridine chemisorbed on Ni( 111) and Ni( 100) surfaces under ultrahigh vacuum. At coverages of 0.5 monolayer, the Raman spectrum is fully developed on the Ni( 100) surface while there is no observable spectrum on Ni( 111). The spectra at saturation coverages are nearly identical. These observations are interpreted as evidence for a higher coverage required for a compressional phase transition on Ni(l 1 1 ), which significantly enhances the Raman intensity.

The 4a, la and 5~ orbitals, and possibly the 2G orbiti, of CO adsorbed on (100) and (111) nickel surfaces, have been detected using both XF'S and faltered UPS techniques. The 30 level was detected only by XPS at = 29 eV with a fti width half-maximum of = 10 to 12 eV. The Cls and 01s binding energy s
