The Angular Overlap Model

In the previous sections we have discussed the ligand-field theory from the point of view of quantum chemistry, and have presented an ab initio derivation of the ligand-field Hamiltonian (1-5). In principle this Hamiltonian can be constructed explicitly using the standard techniques of computational quantum chemistry, although in practice it is evident that this would be subject to the usual difficulties encountered with large molecules. Our concern in this section is with the use of Eq. (1-5) as the basis for a parameterisation scheme that permits the interpretation of the spectroscopic and magnetic properties of transition metal complexes in terms that are chemically intelligible.
