CFT was developed by physicists Hans Bethe [1] and John Hasbrouck van Vleck [2] in the 1930s. CFT was subsequently combined with molecular orbital theory to form the more realistic and complex ligand field theory (LFT), which delivers insight into the process of chemical bonding in transition metal complexes. See more 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 … See more The crystal field stabilization energy (CFSE) is the stability that results from placing a transition metal ion in the crystal field generated by a set of ligands. It arises due to the fact that when the d-orbitals are split in a ligand field (as described above), … See more • Housecroft, C. E.; Sharpe, A. G. (2004). Inorganic Chemistry (2nd ed.).

WebCrystal Field Theory is one of the most accepted theories proposed for explaining the bonding in coordination complexes. It was proposed by Hans Bethe. It treated the atoms as hard spheres and interaction between them is purely electrostatic. The central metal atom has a positive charge and the surrounding ligands have a negative charge.
