Bonding Trends in Molecular Compounds of Lanthanides: The Double‐Bonded Carbene Cations LnCH2+ (Ln=Sc, Y, La–Lu)

“…+ : With a ground state of 4f 12 6s and a promotion energy of 1.24 eV to the first 4f 11 state, we can expect a normal double bond to form, which occurs with a bond energy of 2.15 eV, similar to that of the Dy compound that has a similar promotion energy. However, a single-bonded form was also found with a somewhat larger binding energy of 2.81 eV.…”

“…For some reviews on quantum chemical treatments of lanthanide-containing molecules, see references [5][6][7][8][9]. For more general discussions on the spectroscopic properties of lanthanides see, for example, references [10,11]. For the metals see reference [12], and for general reviews see the Handbook series.…”

Speciation of Uranyl Complexes in Ionic Liquids by Optical Spectroscopy

“…Several reviews describing the luminescence and photophysical properties of the uranyl ion are available. [41][42][43][44] In this paper, the typical spectra of the ligands has a minor influence on the spectral fine structure. The typical spectra of the hydrated uranyl ion as well as of [ …”

Luminescence of Eu(III), Pr(III) and Sm(III) in Carbonate-Fluor-Apatite

“…3b). The lines at 574 nm and 630 nm in both cases have similar decay times of 1.1-1.3 ms (the short decay at 574 nm is connected with uranyl luminescence which is extremely strong in francolite after heating at 800°C [5]), while the line at 616 nm in francolite is characterized by shorter decay of 0.75 ms (Fig. 4).…”
