In molecular physics, crystal field theory (CFT) describes the breaking of degeneracies of electron orbital states, usually d or f orbitals, due to a static electric field produced by a surrounding charge distribution (anion neighbors).
La teoria del campo cristallino, introdotta originariamente dai fisici Hans Bethe e John Hasbrouck van Vleck negli anni trenta, è un modello teorico adottato per interpretare il legame chimico che intercorre nei complessi. Questa teoria rende conto di alcune proprietà caratteristiche di questi composti quali quelle magnetiche, la ...
Crystal field theory (CFT) describes the breaking of orbital degeneracy in transition metal complexes due to the presence of ligands. CFT qualitatively describes the strength of the metal-ligand …
Crystal Field Theory (CFT), introduced in the early 20th century by Hans Bethe and later developed by J. H. Van Vleck and Linus Pauling, revolutionized the understanding of transition metal complexes.
This theory tried to describe the effect of the electrical field of neighboring ions on the energies of the valence orbitals of an ion in a crystal. Crystal field theory was developed by considering two compounds: manganese(II) oxide, MnO, and copper(I) chloride, CuCl.
In this section, we describe crystal field theory (CFT), a bonding model that explains many important properties of transition-metal complexes, including their colors, magnetism, structures, stability, and reactivity.
Crystal field theory views the ions and groups in complexes in terms of their spatial relationships and the interactions based on their electrostatic attraction and repulsion. It is called “crystal field” theory because it derives from a theory developed for the energy relationships of ions in crystals.
