Satellite structures have been observed at 12, 19 and 30 eV below the main peaks in the X-ray photoelectron spectra of the Ti, Sr and O levels of BrTiO3. It is shown that these satellites are attributable to monopole charge transfer shake-up transitions (O 2peg → Ti 3deg, O 2pa1g → Ti 4sa1g, and O 2seg → Ti 3deg, respectively). Charge transfer shake-up satellites have also been observed in the cations and anions of TiO2 and Sc2O3. The first observation of shake-up satellites in the anion levels of these oxides with a 3d0 configuration is additional evidence to support the interpretation that shake-up satellites in transition-metal compounds arise from monopole charge transfer transitions. In general, the first shake-up satellite occurring on the high binding energy side of the transition-metal compounds can be attributed to 2peg → 3deg monopole charge transfer transitions because the probability of the first allowed shake-up, 2pt2g → 3dt2g, is very low.
