Core level photoemission of the no dimer: Theory and Experimental realization for NO/Ag(111)

Energies and XPS intensities of the three lowest N(1s) and O(1s) core-hole states of (NO)2 were calculated within the MC SCF framework. Relaxation effects which produce strong satellite structure, not present in the NO monomer, are characterized in terms of inter- and intra-unit screening. The results agree with the spectra of condensed NO on Ag(111), proving a dimer structure. © 1984.
