The Raman Scattering of Actinide (VI) Ions in Carbonate Media

Raman scattering of actinide (VI) ions from carbonate media were obtained. Results indicate bidentate complexation of carbonate and linear geometry for the AnO22+ ions. The trend of the frequency position of the ν1 vibration in AnO22+ ions is U > Np > Pu > Am in both acid and basic solutions, with higher frequencies occurring in acid media.
