โฆ Synopsis
Exatiination of the various &r&ions liable to contribute to stetite profiles in X-ray photoelectron spectra of 3d-transition metal compounds is intended Lo show the inadequacy of the monopble selection rule which has been wed to account for the app.zrent conelztion between satellite!; and pammagnetism.

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
