Cluster embedding of ionic systems: Point charges and extended ions
This article presents a detailed analysis of the orbital energies of a representative cluster model of a high spin metal oxide, FeO, that has been made to determine the importance of different embedding schemes to represent the extended oxide crystal. The embedding of cluster models of oxides with point charges and with extensions of the embedding which take into account the spatial extent of the cations is examined with an emphasis on the consequences of this embedding for the relative ionization and excitation energies that are measured in core-level spectroscopies.
