The coordination parameters obtained from curve fitting of EXAFS
Sample (fresh) Shell N R(Å) σ22) E0(eV)
Ti–N(O) 3 1.87 0.0029 −3.1
Ti–P 2 2.38 0.0057

Shell indicates the type of ligands for each shell of the fit, N is the coordination number, R is the metal-scatterer distance, σ2 is a mean square deviation in R and ∆E0 is the shift in E0 for the theoretical scattering functions. Numbers in parentheses were not varied during optimization

The errors of data and fits are roughly estimated from the change of the residual factors to be 5% for N, 0.25% for R, 10% for σ2 and 4 eV for ∆E0. No ambiguities of the theoretical standards are included
