Abstract

High-resolution ${L}_{2}$,3 x-ray absorption data are presented for nickel dihalides and nickel oxide. The near-edge multiplet splitting is observed to decrease rapidly with decreasing anion electronegativity. This decrease is accompanied by an increase in a satellite feature. A detailed analysis of the data in terms of recently proposed many-body theories is presented and is shown to yield excellent agreement with experiment allowing a determination of the charge-transfer energy, the d-d Coulomb interaction, and the Ni d--anion p hybridization interaction. We show that the values obtained are in good agreement with those obtained from x-ray photoelectron spectroscopy even though the spectral shapes are strongly different. The difference in spectral shapes is shown to be due to the very different final states.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
