WebIn ligand field theory. …theory evolved from the earlier crystal field theory, developed for crystalline solids by the U.S. physicist Hans Albrecht Bethe. Bethe’s theory considers the metal–ligand linkage as a purely ionic bond; i.e., the bond between two particles of opposite electrical charges. It further assumes that the electronic ... 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.
