Abstract:
A model is described for the calculation of the principal magnetic suscepti- bilities of exchange-coupled binuclear cobaltii species. The two-centre exchange calculation is performed within a basis constructed from appro- priately antisymmetrized products of the one-centre functions belonging to the 4F +4P terms. The exchange parameters refer to interactions be- tween separate one-centre orbitals, in the spirit of Anderson's kinetic and potential exchange pathways, so bearing some resemblance to the angular overlap parameters used to describe the one-centre, ligand-field perturbation.
