Crystal Field Theory - The Limitations of Crystal Field Theory
WebApr 5, 2024 · One of the main limitations of crystal field theory is that it can not explain why certain ligands are strong field ligands and some are weak field ligands. For example water is a strong field ligand. It splits metal orbitals to a greater extend than hydroxyl ion. Crystal field theory could not explain the reasob for such variations. WebNov 29, 2024 · Crystal Field Theory: This theory was developed by Hans Bethe (1929) and John Van Vleck (1932). The main postulates of this theory are- ... Similarly, CFSE for tetrahedral complexes can be calculated by using the formula-(CFSE) th = -0.6(eg) n + 0.4(t 2 g) n (2) It helps us to explain the formation of low spin and high spin complexes.
