Raw EXAFS spectra (a) and processed k3χ(k) data (b) of an inhomogeneous Ti-containing compound measured in the presence of various implementations of the feedback scheme as presented in this paper. For clarity, the k3χ(k) curves have been smoothed. (c) Modulus of the corresponding Fourier-transformed k3χ(k) spectra (in the Δk = 2.0–10.0 Å−1 range). In all parts the same colour coding has been adopted. (d) k3χ(k) experimental spectrum collected with both feedbacks, overlapped with the two main first-shell contributions, as calculated by FEFF-6 code (Ankudinov et al., 1998) through the Artemis interface (Ravel & Newville, 2005): chlorine (orange) and oxygen (cyan). |
