Absorption Spectra of Lanthanide Complexes in Solution

Interpretation of europium(III) spectra

“…Hypersensitive transitions are one of the most intriguing phenomena in lanthanide Much attention has been paid in the literature to the explanation of the phenomenon of hypersensitivity, but there is still no commonly accepted theory [83,94,127,735]. It is safe to conclude that different factors contribute to the intensity of hypersensitive transitions, and that it is not possible to correlate hypersensitivity with just one experimental parameter, such as the symmetry of the Eu 3+ site or the polarizability of the ligands.…”

Bimetallic isopropoxides M[Al(OC3Hi7)4]3 (M = Pr, Nd)—catalyzed reduction of 2-octanone and benzophenone

“…We have also made similar observations during the spectral intensity data analysis for a number of complexes of varying structural features, binding abilities, and different compositional and conformational characteristics in solution and shown that minor changes due to these characteristics are accompanied by significant variation in the oscillator strength of different 4f -4f bands as well as remarkable variations in Judd-Ofelt (T λ ) parameters [38][39][40][41][42][43][44]. The present investigation, perhaps, is the first to report the MPV reduction of ketones using heterobimetallic isopropoxides, M[Al(-OC 3 H i 7 ) 4 ] 3 , as homogeneous catalysts.…”

Spectroscopic Studies of Lanthanides Ion in High-Temperature Molten Salt

“…The predicted energies were compared with the available experimental data. Mirsa and Sommer published a review paper regarding lanthanide spectroscopy at room temperature in an aqueous solution (9). This review paper contains various aspect of lanthanide spectroscopy including details of the hypersensitive transition.…”

“…The chemical behavior of lanthanides elements in various environments has been particularly important in fundamental aspects as well in various fields, such as optical, nuclear, and biophysics applications (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11). Therefore, many spectroscopic studies on lanthanides in aqueous media have also been published along with several review papers (5-7, 9, 10).…”
