The electronic structure of alkali metal oxides

Crystalline phase total energies, band structures, the distributions of the total and partial densities of electron states, and atomic charges were calculated for lithium, sodium, and potassium oxides, peroxides, superoxides, and ozonides using the CRYSTAL 06 and GAMESS packages in the B3LYP parameterization. For the molecular phases, the geometry was optimized and molecular orbital energies calculated. The results obtained for metal oxides were compared with the experimental photoelectron spectroscopy data and used to analyze their formation and thermal decomposition.
