Figure 7
Cross-fits of k2-weighted XAFS spectra using Hybrid (HPA) non-interpolated data with refined structures from Table 4. Top row: i-pr experimental data; bottom row: n-pr. Left column: fitted with the optimized tetrahedral structural model; right column: fitted with the optimized square-planar model. The black line is a Hanning window and indicates the region over which the fit is performed. Inferior fits are obtained when alternate FEFF structure geometry is applied in (b) and (c), as detailed in Table 4. |
