Analysis of silica-supported vanadia by X-ray absorption spectroscopy: Combined theoretical and experimental studies

environmental studies of iron in sediments by means of x-ray absorption spectroscopy

x-ray absorption fine structure (xafs) spectroscopy was used to identify directly the metal speciation and local bonding environment of fe in sediments originated from dobczyce reservoir (poland); special attention was paid to analysis of samples collected from points situated at different distances from the land. the combination of traditional approach to data analysis as well as usage of mult...

Experimental and Theoretical Investigations of Metalloproteins using X-ray Absorption Spectroscopy

X-ray Absorption Spectroscopy

X-ray absorptioń spectroscopy, today widely used as a tool for structural investigations, is described. Theoretically it is shown that above an absorption edge the absorption coefficient is well approximated by a sum of terms, each one describing a particular path followed by the photoelectron outgoing from the atom. Such geometrical feature allows to use X-ray absorption spectroscopy for struc...
