In Article I, we showed that the freeon‐exchange theory of magnetic coupling is a viable alternative to the widely used spin‐exchange theory. In Article II, we are concerned with the symmetric‐bridge, molecular magnet, AXB, where A and B are magnetic atoms and X is the bridge. The symmetric‐bridge molecular magnet is of particular interest because the major features of its spectrum and its coupling constants are obtained by means of the two‐electron, two‐site freeon theory. We exhibit one example of ferromagnetic coupling, J>0 and one of antiferromagnetic coupling, J<0. © 1997 John Wiley & Sons, Inc. Int J Quant Chem 65 : 299–304, 1997
