Résumé

A high energy resolution x-ray absorption near-edge structure (XANES) spectroscopy study on U4⊃+ (UO₂), U5⊃+ ([UO₂ Py₅] [KI₂ Py₂]), and U6⊃+ [UO₂ (NO₃) 2 (H₂ O) 6] demonstrates the potential of this experimental technique for qualitative/semiqualitative and quantitative actinide speciation investigations. We observe a pre-edge feature with quadrupole nature in a U L₃ edge partial fluorescence yield-XANES spectrum. This feature is a tool for characterizing the participation of 5f orbitals in U-O bonding. The feature origin is explained by performing calculations with the finite difference method near-edge structure code based on the multiple-scattering theory and the finite difference method.
