The x-ray photoelectron spectra of 18 compounds of uranium have been studied in the range of binding energies from 0 to 1100 eV. It has been established that the intensity of the line of the U 5f electrons not participating in chemical bonding, the position and intensity of the shake-up satellites of the levels of the deep uranium electrons, the splitting of the levels of the inner valence MO's appearing as a result of the interaction of the U 6p and O 2s AO's, and a number of other parameters of the spectrum of oxygen-containing compounds of uranium depend on the oxidation state of the latter. It has been postulated that one of the reasons for the appearance of the complex structure of the lines of the U 4p, 5s, 5p, 5d, and 6s electrons, which is characteristic of the spectra of the compounds studied, is the configuration interaction. The tendency for lowering of the levels of the electrons of uranium in the spectra of uranyl complexes with an oxygen environment around the central ion as the strength of the equatorial ligands is increased has been noted.
