The relative contributions of covalent, electrostatic and other interactions to the CF are not known a priori. The existent models include exclusively either covalent (angular overlap model [42-44] or electrostatic [40, 41, 45] interactions, which seems unjustified.)... 

The term angular overlap model was first used in 1965 to describe a more general treatment, which may also be called the model (12,13). The relative energies of the orbitals in a partly-filled /-shell are expressed in terms of the parameters ex (X = a, rr, etc.), whose coefficients can be calculated from the geometry of the system. The eK model was developed from perturbation theory, but is equivalent to the E2 model when only a-overlap is considered, and to the Yamatera-McClure model for orthoaxial chromophores with linear ligators. The notation ex is often used, where ...
