Figure 5From: Quantum mechanical calculation of aqueuous uranium complexes: carbonate, phosphate, organic and biomolecular species(a) Observed Raman spectrum of uranium-oxalate 1:1 solution at pH 10. (b) Calculated Raman spectrum of UO2(OH2)4(C2O4)•30(H2O) (UO2Ox-W30) shows a sharp peak near 1800 cm-1 indicative of C=O bonds that would be present if oxalate forms a bidentate complex with uranyl.Back to article page
