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).

Page ID. 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.
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. CFT focuses on the interaction between the d-orbitals of the central metal ion and the ligand field generated by surrounding ligands.
1 de oct. de 2022 · 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. Yet this rule fails many times, especially in phosphors with low-symmetry sites.
