Pu L3 X-ray absorption fine structure spectra from 24 samples of PuO2+ x (and two related Pusubstituted oxides), prepared by a variety of methods, demonstrate that (1) although the Pu sublattice remains the ordered part of the Pu distribution, the nearest-neighbor O atoms even at x) 0 are found in a multisite distribution with Pu-O distances consistent with the stable incorporation of OH- (and possibly H2O and H+) into the PuO2 lattice; (2) the excess O from oxidation is found at Pu-O distances
