Charge transfer shake-up satellites in X-ray photoelectron spectra of solid compounds of 3d 0 ions

Abstract

Satellite structure has been observed at 8 eV and 12 eV below the main metal 2p peaks for compounds of Sc 3+ and Ti 4+. These features are attributed to charge transfer “shake-up”: transitions (t 2g → t 2g * and e g → e g * respectively). The 8 eV satellites are only found in sulphate complexes of Sc 3+. This is the first observation of satellites which are probably due to t 2g → t 2g * monopole charge transfer transitions. The probability for this transition is usually low, resulting in the observation of satellites due to the e g → e g transition.
