Although it fails to explain certain cases, such as the strong bonding of the low-dipole carbonyl group, it successfully explains many other chemical properties. The crucial parameter is delta, which is compared with the energy cost of having two electrons in the same orbital. If delta, which measures the difference in energy levels created by the presence of ligands, is large, electrons in the central metal atom are forced into the lower of the d energy levels, explaining many of the anomalous properties of metal complexes.
