摘要

Structural Chemistry of the Lanthanideslevant complexes with only inorganic ligands have been included. Organolanthanides are divided into the cyclopentadienides, σ-bonded compounds, and the cyclooctatetraene complexes. A brief discussion of the covalent contribution to the bonding in organolanthanides is included. The coordination compl

Magnetic Properties of Lanthanide Compoundshe characteristic properties encountered in such compounds. After a brief survey of the crystal field theory and the interaction mechanisms, we will present successively the problems related to the magnetic anisotropy, the nature of the magnetic ordering, the dipolar ordering, the anomalous rare ear

Optical Spectroscopy of Lanthanides in Crystalline Matrixe crystal field spectra in imperfect crystals are discussed. Intensities and linewidth are considered. The spectroscopy of solids employing lasers is described followed by the consideration of hyperfine interactions, energy transfer and glasses contains RE’s. Finally divalent RE ions and magnetic in

Spectroscopic Properties of the f-Elements in Compounds and Solutions summarize the present status of our energy level calculations in single crystal matrices and in aqueous solution, and compare the predicted crystal-field structure in certain low-symmetry sites with that observed. Some interesting new structural insights are thereby gained. The state eigenvectors f

The Lanthanides as Geochemical Tracers of Igneous Processes: An Introductionals of the Earth’s crust. The concept of mineral/melt distribution coefficient, which can be determined experimentally, permits the use of mathematical models to describe in a more quantitative way partial fusion and crystallization. This leads to a better understanding of the petrogenetic mechanism

Lanthanoids as a Geochemical Probe and Problems in Lanthanoid Geochemistry Distribution and Behavious as well as in the geochemical traps where the Ca minerals crystallized. A very general model for Ln fractionation is discussed which essentially considers the distribution coefficients to be dependent on the Ln-complexing ligand concentration in the fluids. Its validity is demonstrated by results

Summary and Future Trends in Lanthanidesrage, for magnets and for solid-state lasers. The lanthanide metals will be used more widely for the purification of metals by removal of oxygen, sulfur, and other non-metals. However, their most important application will be in adding to our fundamental understanding of all materials.
