Crystal field meaning
http://gemologyproject.com/wiki/index.php?title=Causes_of_color 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 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.
WebThe energy-level splitting is the crystal field splitting, and it is denoted by Δ with subscripts c, t, o for cubic, tetrahedral, and octahedral crystal fields, respectively.
