Hydration and Hydrolysis, in Handbook on the Physics and
spectra were fit with the R-space X-ray Absorption Package
(RSXAP),43 using parameterized phase and amplitude func-
tions generated by the program FEFF744 with the crystal struc-
tures of uranyl acetate dihydrate and sodium uranyl triacetate.
Standard scattering paths were calculated from the crystal
structures.25–27 In the data analysis, full cluster multiple scatter-
ing calculations were tried, but were found to have no influence
on the best fit parameters and the overall goodness of the fit. As
a result, only the following relevant paths were included in the
calculation: the single scattering interactions of U–Oax (axial
oxygen), U–Oeq (equatorial oxygen) and U–C, and the multiple
scattering of O᎐U᎐O (axial oxygens).
