TLDR
In this article, the correct treatment of the spatial averaging procedure in the EXAFS formalism reveals the need for sizeable corrections in many cases of interest, and the consequences of the new formalism, together with the absence of low momentum transfer information, results in serious limitations in the study of disordered systems by the ExAFS technique.About:

Application of the ratio method of EXAFS analysis to disordered systems
TL;DR: In this paper, when moderate disorder is present, the cumulant expansion/ratio method approach to EXAFS data analysis offers an attractive alternative to nonlinear least-squares fitting of the data Analysis by nonlinear fitting, moment expansion, and Cumulant Expansion are compared, and useful formulae are derived kdependent mean free path is also treated

Structure of Mn and Fe oxides and oxyhydroxides: A topological approach by EXAFS
Alain Manceau,J. M. Combes +1 more
TL;DR: In this paper, it is shown that EXAFS spectroscopy is sensitive to the nature of interpolyhedral linkages relying on metal-two nearest metal distances, and that the proportion of pyrolusite domains within the lattice of nsutite from Ghana is equal to 35±15 percent.

New Technique for Investigating Noncrystalline Structures: Fourier Analysis of the Extended X-Ray—Absorption Fine Structure
TL;DR: In this paper, Fourier analysis was applied to the point-scattering theory of x-ray absorption fine structure to invert experimental data formally into a radial structure function with determinable structural parameters of distance from the absorbing atom, number of atoms, and widths of coordination shells.

TL;DR: In this article, the authors used a Fourier transform to calculate a set of complex phase shifts, which were then applied to the EXAFS problem and obtained excellent agreement in both the amplitude and the phase.

Transferability of Phase Shifts in Extended X-Ray Absorption Fine Structure
TL;DR: In this article, phase shifts in extended x-ray-absorption fine-structure (EXAFS) measurements have been empirically determined for atom pairs for photoelectron energies g 100 eV, which can be used with EXAFS spectra to determine interatomic distances typically to accuracies of 0.02 \AA{}.
