NORONHA, F. B.. EXAFS as a tool for catalyst characterization: a review of the data analysis methods. Braz. J. Chem. Eng. [online]. 1999, vol.16, n.3, pp. 309-317. ISSN 0104-6632.  http://dx.doi.org/10.1590/S0104-66321999000300009.

A review of the EXAFS data analysis methods is presented. A detailed description of the EXAFS signal extraction and the Fourier transform of the data are discussed. The procedure for determining interatomic distances, coordination numbers and disorder effects from EXAFS data is described. This paper also discusses the data analysis statistics. Finally, one example of catalyst characterization by the EXAFS technique is reported.
