Part of the NATO ASI Series book series (NSSB, volume 345)


The X-Ray Photoemission (XP) core level spectra of transition metal (TM) compounds have been intensively investigated with the aim to obtain appropriate parameters to characterise their electronic properties 1–15. In particular, the charge transfer (CT) energy, A, which describes the charge fluctuation from the ligand to the metal according to the mechanism d n d n+1 L and the Mott-Hubbard energy U, which accounts for the electronic charge fluctuation between two transition metal ions in the crystal lattice, \( d_i^nd_j^n \to d_i^{n - 1}d_j^{n + 1} \) are basic concepts to understand the electronic correlations of TM compounds 7–9.
