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

Role of Inelastic Effects in EXAFSch give an energetic photoelectron a short mean free path. The need for including inelastic damping effects in calculations of EXAFS spectra .(.) is graphically illustrated by a comparison of typical results of one-electron theory and experiment (Fig.1).
