An X-ray absorption spectroscopic study at the mercury LIII edge on phenylmercury(II) oxygen species [PDF]
, 2000 The X-ray absorption spectra of the reference and model compounds HgCl2, PhHgCl, PhHgOAc and [(PhHg)2OH][BF4].H2O have been analysed in both the XANES and EXAFS regions, and the technique was extended to determine the structures of (PhHg)2O, PhHgOH, and ...

EXAFS studies on the reduction of palladium(II) in X zeolites [PDF]
, 1986 Palladium tetraammine ion exchange into zeolite, temperature treatments under different atmospheres, and hydrogen reduction have been studied by EXAFS at the Pd Κ edge. Complete autoreduction is found to take place between 473 and 623 Κ under vacuum.

EXAFS spectroscopy of quasicrystals [PDF]
Crystallography Reports, 2007 The results of the investigation of the features of the local structure of quasicrystalline materials by extended X-ray absorption fine structure (EXAFS) spectroscopy with the use of synchrotron radiation are analyzed. The advantages of this method from the point of view of deriving information about the local shifts of the atoms forming an icosahedral

Data analysis in extended x-ray-absorption fine structure: Determination of the background absorption and the threshold energy [PDF]
, 1983 Two approaches for the determination of the background absorption (μ_0) in the extended x-ray-absorption fine structure (EXAFS) are presented. Both methods, experimental and computational, take advantage of the damping of the EXAFS amplitude resulting ...
