The difference of energy between these two sets of orbitals is called crystal field splitting energy. (Δ0 for octahedral complexes).
WebMay 6, 2024 · 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. WebThe crystal field theory was proposed by Hans Bethe and VanVleck. This theory gives satisfactory explanation for the bonding and the properties of complexes than the valence bond theory. Assumptions of Crystal field theory: The interaction between the metal ion and the ligand is purely electrostatic.
