In situ photoelectron spectroscopy studies in ultrahigh vacuum of the electronic structure of the surface of molybdenum oxidized in air and during the adsorption of sodium Na with submonolayer coatings were carried out. The spectra of photoemission from the valence band and the core levels O 1s, O 2s, Mo 4s and Na 2p were studied under synchrotron excitation in the photon energy range of 80 – 600 eV. The change in the spectrum of the oxygen core levels associated with the substitution of hydrogen atoms in the hydroxyl group by sodium atoms was found. The surface topography and cathodoluminescence of molybdenum oxide were studied.
