β¦ Synopsis
XPS and UPS studies of xenon adsorbed on and implanted into Ni (100) and Ni (11 I) surfaces indicate that the sum of the potentil and relaxation shifts (1.1 to 1.3 eV) is similar for both core and valence levels. The binding energies of the core and valence levels are systematicaIiy lower for Xe adsorbed OR the Ni (11 I) surface. The levels are alI broadened by similar amounts compared to gas phase xenon.

The monolayers of 2-mercaptobenzothiazole (MBT) on polycrystalline Au and Ag films have been studied by surface-enhanced Raman (SERS) and X-ray photoelectron (XPS) spectroscopies. Whereas MBT adsorbs with its molecular plane flat on Ag, its plane is perpendicular on Au. This difference in adsorbate
