We present the results of photoemission studies of valence disordered'' monoclinic BaBiO{sub 3} in the photon energy range 15--120 eV. The line-shapes of the valence band photoemission spectra and the Ba contributions to the valence band are very similar to the line shapes of the total density of states and Ba partial density of states, respectively. Oxygen resonance is observed, demonstrating the existence of empty O 2p states. These results support a more covalent rather than a simple ionic picture for the electronic states of BaBiO{sub 3}.
