Near-Edge X-Ray Absorption Spectroscopy of Catalyst-Related Matter 

The capabilities of near-edge X-ray absorption spectroscopy that make it suited for structural studies are the following  

X-Ray absorption data in combination with atomic theory and solid-state band-structure theory can yield detailed information about the ground-state electronic structure of solids on an energy scale on the order of meV. This holds particularly true for correlated narrow-band systems, such as the rare-earth and transition-metal compounds. In broad-band materials, such as the 

Currently the feeling is that more structural information, for example, locations and site symmetries of the atoms in a particular shell, is contained in the XANES region of an edge absorption spectrum than in EXAFS. However, the large cluster size ( 102 atoms) required for XANES calculations is a considerable drawback.
