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).
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 bonds. Based on the strength of the metal-ligand bonds, the energy of the system is altered.
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. The central assumption of CFT is that metal–ligand interactions are purely electrostatic in nature.
Learn about crystal field theory, which describes the interaction of d orbitals of a transition metal ion with ligands. Find out how crystal field splitting, high spin and low spin, and crystal field stabilization energy affect the properties of complexes.
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.

1 de oct. de 2022 · open access. Abstract. Crystal field theory has been widely adopted to study the structure–property relationships in luminescent materials. It has the advantage of simplicity and clarity, i.e., the total crystal field splitting is reciprocally proportional to the 5th power of bond length.
