INTERPRETATION OF EXAFS DATA

An outline of the theory of X-ray absorption as applied to X-ray absor ption spectroscopy is given, concentrating on EXAFS, showing how struc tural parameters are contained within the theory. A full description o f the scattering problem and of inelastic effects is also included, an d a description is given of how structural information may be extracte d from experimental data. The emphasis is on curve-fitting methods, in cluding those techniques which allow the inclusion of external constra ints.
