| Abstract: | X ray photoemission spectra measurements were carried out to elucidate the valence band picture and bonding characters of
the two dimensional semiconductor red bronze K0.33MoO3. The valence band spectrum is similar to that of measurement of UPS, and in agreement with the molecular orbital model presented
by Travaglini. Asymmetric and broadening line shape of O-1s means the presence of several inequivalent bonds of oxygen. Mo-3d
core-level spectrum reveals that there are two kinds of valence states of molybdenum (Mo+5, Mo+6), and that its average valence state is +5.42.
