X-RAY-ABSORPTION NEAR-EDGE STRUCTURE SPECTRA FOR BULK MATERIALS - MULTIPLE-SCATTERING ANALYSIS VERSUS A PHENOMENOLOGICAL APPROACH

X-ray-absorption near-edge structure data evaluations, based on a simple approach to determine bond lengths directly from features of the spectra, have frequently been reported in the literature. This approach is discussed critically taking into account multiple-scattering calculations as well as previously published experimental and theoretical data. All results together demonstrate that this approach can be used for simple molecules, but becomes questionable for condensed-matter analysis.
