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). This theory has been used to describe various spectroscopies of transition metal coordination complexes, in particular optical spectra (colors). CFT successfully accounts for some magnetic properties, colors, hydration enthalpies, and spinel structures of transition metal complex… WebCrystal field theory (CFT) describes the breaking of degeneracies of electron orbital states, typically d or f orbitals, caused by a static electric field generated by a surrounding charge distribution (anion neighbours). …
