The difference in energy between the e g and the t 2g orbitals is called the crystal field splitting and is symbolized by Δoct, where oct stands for octahedral. The magnitude of Δ oct depends on many factors, including the nature of the six ligands located around the central metal ion, the charge on the ... WebThe Crystal Field Theory (CFT) is a model for the bonding interaction between transition metals and ligands. It describes the effect of the attraction between the positive charge of the metal cation and negative charge on the non-bonding electrons of the ligand.
