WebCrystal 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). WebAccording to crystal field theory, the five 3d orbitals of first series transition metal ions are split into two energy levels when the cation is surrounded by ligands (e.g. oxygen anions). In octahedral coordination, three of the 3d orbitals (the taP. set) are stabilized relative to the other two (the e, set), the energy separation (crystal ...

WebThe crystal field theory (CFT) was developed for crystalline solids by the physicist Hans Bethe in 1929. The model takes into account the distance separating the positively and negatively charged ions and treats the ions simply as point charges with the attractive and repulsive interactions between them as purely electrostatic/ionic ones.
