VALENCE ELECTRONIC-STRUCTURE OF URANYL-NITRATE UO2(NO3)(2)CENTER-DOT-2H(2)O

Experimental and theoretical studies on the electronic structure of a uranyl nitrate hydrate, UO2(NO3)(2) . 2H(2)O, have been performed by X -ray photoelectron spectroscopy (XPS) and with relativistic DV-X alpha molecular orbital methods. The XPS spectra are measured within five m inutes of X-ray irradiation, which causes negligible damage to the sam ple. Taking into consideration the calculated results, each peak of th e experimental spectrum is assigned. The theoretical spectrum of the u ranyl nitrate is in good agreement with the present experimental spect rum.
