An XPS study of an isomorphous trivalent lanthanoid series

X-ray photoelectron spectroscopy has been used to investigate the core electron binding energies within an isomorphous series of lanthanoid complexes; [LnL(1)] where Ln=La-Lu (except Pm) and H3L is the heptadentate ligand 2,2',2-tris(salicylideneimino)triethylamine. This study also examines spin-orbit coupling of the trivalent lanthanoids bound to this organic ligand and addresses the issue of satellite peaks in the spectra. (C) 2002 Elsevier Science B.V.
