Comparison of 7F ←5DO emission spectra for Eu(III) in crystalline environments of octahedral, near-octahedral, and trigonal symmetry

Chemical Physics Letters, 1983
Abstract Isotropic 7FJ←5DO emission spectra are reported for Eu(III) in four different crystalline system. These systems differ with respect to Eu(III) site symmetry, coordination number, coordination geometry, and the chemical nature of the coordinated ligands.

Comparative energy level parametrizations for lanthanide ions in octahedral symmetry environments

Journal of Alloys and Compounds, 1995
Abstract New experimental datasets are presented for the energy levels of tripositive lanthanide ions situated in octahedral symmetry environments, in elpasolite lattices. The freely varying atomic parameters derived from energy level parametrizations of the new datasets show empirical relations with atomic number. The magnitudes of the crystal field

Direct measurement of octahedral and tetrahedral site environments in NiZn-ferrites

IEEE Transactions on Magnetics, 1995
The local environment of metal ions in a series of spin-sprayed Ni/sub 0.15/Zn/sub y/Fe/sub 2.85-y/O/sub 4/ (y=0.16, 0.23, 0.40, 0.60) films have been studied using extended X-ray absorption fine structure (EXAFS). Fourier transforms of the EXAFS data show peaks which are identified with specific local atom correlations within the spinel ferrite unit ...

Hyperfine electric field gradients and local distortion environments of octahedrally coordinated Fe²⁺

American Mineralogist, 2005
We report ab initio electronic structure calculations that directly relate given local chemical and distortion environments to corresponding hyperfine electric field gradients (EFGs) in 5 7 Fe Mossbauer spectroscopy, thereby giving needed interpretive power to the technique in characterizing V I Fe 2 + environments in minerals. Changes of the EFG

The NMR isoshielding diagram for an f-electron system in a crystal field environment of octahedral symmetry

Journal of Magnetic Resonance (1969), 1982
Abstract A general expression using a nonmultipolar expansion technique is derived for the NMR shift resulting from the f -electron orbital angular momentum and the f -electron spin dipolar-nuclear spin angular momentum interaction, where the f electron is in a crystal field environment of octahedral symmetry.
