Photoemission and bremsstrahlung isochromat spectra have been measured on TiO2 (rutile) and SrTiO3. The magnitudes of the fundamental band gaps estimated from the combined spectra agree well with the results of the photoabsorption and the energy-band calculations. The profiles of the observed spectra do not reveal the fine structure expected to occur in the density-of-states curves obtained by the energy band calculations, suggesting the existence of a mechanism to smear out the fine structure considerably. The combined spectra are used to interpret the charge-transfer-type satellite manifest in the core-level spectra. For 3s photoemission, satellite features ascribed to the configuration interaction between the 3s3p6 and 3s23p43dstates in the atomic notation are also observed.
