INTERPRETATION OF EXAFS DATA

An outline of the theory of X-ray absorption as applied to X-ray absorption spectroscopy is given, concentrating on EXAFS, showing how structural parameters are contained within the theory. A full description of the scattering problem and of inelastic effects is also included, and a description is given of how structural information may be extracted from experimental data. The emphasis is on curve-fitting methods, including those techniques which allow the inclusion of external constraints.
