Abstract
XPS, UPS, and XAES spectra from nitrogen adsorbed on W(110) at 100 K have been measured. The combination of the spectra gives a clear fingerprint of chemisorbed nitrogen molecules which should be useful for identification of adsorbed N//2 in other systems. The results suggest that in the present case the nitrogen molecules are adsorbed with their axis perpendicular to the surface. Comparison of the UPS and XPS valence spectra from the adsorbed N//2 molecules allows the assignment of the adsorbate valence peaks to 4 sigma and 1 pi plus 5 sigma levels which have similar energy separations to those found for adsorbed CO.
