WebCrystal field theory (CFT) is a bonding model that explains many properties of transition metals that cannot be explained using valence bond theory. In CFT, complex formation … WebOct 19, 2016 · Crystal Field Theory: Crystal field theory has several limitations. It takes into account only the d-orbitals of the central atom; the s and p orbitals are not considered. In addition, this theory fails to explain the reasons for large splitting and the small splitting of some ligands.
