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.
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.

The crystal field theory is based on the assumption that the chromophore {MLn } of a coordination compound can be described by the model according to which the central atom with its valence d -orbitals is under the influence of point charges generated at the ligand positions.
Learn how the electrical field of neighboring ions affects the energies of the d orbitals of a transition-metal ion in a crystal. Explore the splitting of d orbitals in octahedral, tetrahedral, and square-planar complexes, and the spectrochemical series.
