Fig. 6. Real component of Fourier transform of EXAFS spectra after subtraction of the U-oxo contribution. These are dominated by the components of the equatorial O contribution. (a), and (b) are, respectively, groups 1 and 2. The listed numbers for each sample show the shorter U–Oeq distance, the separation between this one and the next longest one that can be compared with the 0.12 Å resolution limit, and the ratio of their two numbers that does not account for differences in the Debye–Waller factors. The dashed lines are guides to the positions of particular features discussed in the text.
