1956 Nature 18 Feb. 305/2 A proper consideration of the effect of the ligand~field explains why the six-coordinate complexes of nickel are equally stable with the cupric complexes.

1960 L. Pauling Nature Chem. Bond (ed. 3) v. 174 In some respects the ligand field theory is closely related..to the valence bond theory.

1966 F. A. Cotton & G. Wilkinson Adv. Inorg. Chem. (ed. 2) xxvi. 661 This modified CFT [sc. crystal field theory] is often called ligand field theory, LFT. However, LFT is sometimes also used as a general name for the whole gradation of theories from the electrostatic CFT to the MO [sc. molecular orbital] formulation.

1970 W. L. Jolly Synthesis & Characterization Inorg. Compounds xxii. 324 If we were able gradually to decrease the ligand field strength to zero, we would find that each term would gradually approach an energy corresponding to one of the states of the free ion.

1971 Orchin & Jaffé Symmetry, Orbitals & Spectra vii. 170 Interpretation of the spectra of inorganic complexes is greatly simplified and successfully integrated by the use of ligand field theory.
