Satellite structure has been obsezved at 8 eV and 12 eV below the main metal 2p peaks for compounds of Sc3+ and Ti4+. These futures are attributed to charge transfer "shake-up" transitions (tag + tzg and eg -+ eg respectively). The 8 eV satellites are only found in sulphate complexes of Se3' \_ This
The extra peak. located at LX 13.6 eV on the high-bilidin~~ner~y side of the cure levels cf titenium in rutile, : anafase and barium titanate, probably arises from a shake-up process involving an O(2p) -, Ti(4s) transition. :
The structures of the satellites accompanying the Br 3p, Br 3d, K 2s and K 2p peaks of the X-ray photoelectron spectra OF KBr were investigated. It is shown rhat these satellites are not simply due to discrete photoelectron
