ALKALI METAL OXIDES - OCCUPIED, UNOCCUPIED AND EXCITED STATES
The occupied and unoccupied electronic states of NaO-2 and KO-2 have been investigated by UV photoemission spectroscopy and inverse photoemission spectroscopy, respectively. In addition single electron excitations from occupied into empty levels have been probed by X-ray absorption and electron energy loss spectroscopy. The experimental data are augmented by LCGTO-"sl X/"alpha model cluster calculations. A detailed assignment of initial and final states is given. The excitation cross sections and an inversion of the ligand field induced 3"it d/" level splitting in NaO-2 are discussed.
