Experimental (solid) V K edge FT(χ(k)*k3) of dehydrated V
/SBA-15 (10.8 wt %) together with a theoretical XAFS function (i.e. "ordered arrangement of V
" model). Fitting results are given in Table 2. Inset shows a schematic representation of arrangement of V2O7 units in Mg2V2O7. Also shown are the Fourier transformed χ(k)*k3 of the individual scattering paths together with corresponding coordination number in brackets.
