Opis:: Electronic absorption spectra of erbium and dysprosium acetate single crystals were measured. The intensities of 4f-4f transitions were calculated and the Judd-Ofelt Ω$\text{}_{λ}$ parameters evaluated. Heavy lanthanide acetates differ from other lanthanide carboxylate compounds by relatively high "hypersensitive" transition intensities and the Ω$\text{}_{2}$ parameters. These results are discussed in terms of a stronger polarization effect which can be explained by the distinctly shorter Ln-OH$\text{}_{2}$ bond in comparison with the Ln-OOC bond in the investigated system.

Opis:: Absorption spectroscopy was used to study the aqueous solution structure of Eu(III) complexes with DTPA (diethylenetriaminepentaacetic acid) and TTHA (triethylenetetraaminehexaacetic acid). Analysis of the oscillator strengths of the 4f ↔ 4f transitions and of the Judd-Ofelt intensity parameters, τ$\text{}_{λ}$, was performed in order to investigate the formation and the type of bonding in Eu(III)-DTPA and Eu(III)-TTHA species occurring in solution. The correlation of these results with those from other methods made it possible to suggest a relatively complete model of Eu(III)-polyaminocarboxylate coordination.
