Thermodynamik chemischer Reaktionen,ces, we shall present here the spectra of the vanadyl and thiovanadyl(IV) 2,3,7,8,12,13,17,18, octaethylporphyrin (V=O:OEP, V=S:OEP). As a typical illustration of the so-called focusing effect in the colinear arrangement of two scatterers we shall also reproduce the EXAFS spectrum of the dibromovanadium(IV) OEP complex.

EXAFS and XANES are becoming interdis­ ciplinary methods used in solid-state physics, biology, and chemistry, and are making impressive contributions to these branches of science. The present book gives a panorama of the research activity in this fie

The Transition Region Between XANES and EXAFS structural sensitivity is an electron emitted from an inner shell: the scattering of this electron modulates the absorption cross section. Figure 1 shows a typical X-ray absorption cross section and makes the somewhat arbitrary distinction between X-ray absorption near edge structure (XANES) and th

Furthermore, the very same advantageous characteristics of EXAFS (short-range, single-scattering) are also its serious limitations: distance det
