AbstractThe X‐ray absorption near‐edge structure (XANES) of transition metal oxides is analyzed in terms of scattering resonances from neighboring atoms. Spectra from reference compounds of simple, known structure were used to facilitate identification of XANES peaks with scattering from specific coordination spheres.

X-ray Absorption Spectroscopy of CuO2 Chains
Journal of Low Temperature Physics, 2003The electronic structure of various edge-shared chain compounds A1−x CuO2 (A=Ca,Sr,Ba) was studied by O-K and Cu-L3 x-ray absorption spectroscopy and exact diagonalizations techniques. The doping-dependent behaviour in these chains differs from that of conventional 2D Cu-O networks of cornershared CuO4 plaquettes due to the much smaller inter-plaquette

Recent advances in x-ray absorption spectroscopy
Reports on Progress in Physics, 2004Using x-ray absorption spectroscopy recent progress is achieved all over in solid state physics. This review focuses on these advances, with particular emphasis on applications to surface physics and to magnetism of ultrathin 3d and 5d films that are made possible by the use of undulators in third generation synchrotron radiation sources: the ...

X-Ray Absorption Spectroscopy: EXAFS and XANES
1994The discovery of X-rays by Roentgen in 1891 allowed study of crystalline materials on an atomic scale. The X-ray energy range is of the order of 1 keV, which corresponds to wavelengths of 10 A.

Glancing Angle X-Ray Absorption Spectroscopy
Advances in X-ray Analysis, 1990AbstractThe use of glancing angles of incidence enables X-ray Absorption Spectroscopy to be measured as a function of depth from the surface of a material into the bulk. As x-rays rather than photoelectrons are detected, a UHV environment is not required and instead surfaces and interfaces can be examined under realistic operational conditions.

X-ray Absorption Spectroscopy: Soft X-ray Absorption Methods
2004Probing events that occur in a catalyst under working conditions is a very important scientific topic. In order to identify reaction intermediates and active sites in a catalyst, characterization techniques should be further developed and consequently the design and construction of appropriate in-situ cells and reactor probes are inevitable.
