Excited states of cerium (III) in various local symmetries by UV absorption and luminescence spectra
نویسنده
چکیده
Among trivalent lanthanides,cerium has the lowest-lying 5d 1 configuration with up to five distinct Kramers doublet energies,strongly separated by chemical bonding of the same kind as known from Re,Os,Ir,pt complexes with ground configuration 5dq,but with more moderate spin-orbit coupling effects in Ce. Lanthanides rather indifferently show all the coordination numbers N from 6 to 12 (11 for CeF ) and elastic internuclear distances. Stokes shifts can only be superficia?ly rationalized with one configurational coordinate out of many.

ABSTRACT The solvatochromic behaviour of two ketonic derivatives of benzodiazepine namely 7-chloro-1-methyl-5-phenyl-1,5-benzodiazepine-2,4-dione (Clobazam®) and 5,(2-chlorophenyl)-7-nitro-2,3-dihydro-1,4-benzodiazepine-2-one (Clonazepam®) were analysed in some selected solvents of different polarities using UV-Visible spectroscopy and DFT computational techniques. The solute-solvent interacti...
متن کاملMicroscopic Parameters in the Excited State of Toluene and Some of Its Haloderavatives
The Ultraviolet-visible (UV) spectra of toluene, ortho-bromo and para-bromo toluene in different solvents have been studied. The electric dipole moments and polarizabilities in the molecular excited electronic states were determined. It was found that the electric dipole moments for the excited states (µ*) and the ground states (µ) of these compounds are equal, and the change in dipole moment i...
متن کاملDendrimers made of porphyrin cores and carbazole chromophores as peripheral units. Absorption spectra, luminescence properties, and oxidation behavior.
Luminescent and redox-active porphyrin-based dendrimers of first and second generation have been synthesized, and their absorption spectra, photophysical properties, and oxidation behavior have been investigated, together with those of the corresponding aldehyde carbazole precursors. All the dendrimers contain a porphyrin core and carbazole-based chromophores as branches. The structural formula...
متن کاملA new method for Eosin preparation and examination of its absorption and emission spectra
Eosin is one of the original dyes of xanthenes derivatives. It is also one of the main derivatives of fluorescein and has brilliant fluorescence. Eosin disodium salt called "Eosin Y" is the most useful form of this compound. In common procedures, eosin is usually obtained by the action of bromine on fluorescein, which has not good yield and purity degree. In this research, it is prepared by the...
