There are 21 combinations of heterospin dinuclear systems between SA = 1/2 and SB = 7/2 local spins. The zero-field energy levels of the coupled systems can be generated in the same way as in the previous case of homospin systems. The result is... [Pg.629]

The formula just derived for the magnetic susceptibility of heterospin systems is applicable also to the special case of homospin systems when the g-factors differ from each other. Notice that... [Pg.640]

Isotropic exchange in heterospin dinuclear complexes differs from the homospin case in that the second-order van Vleck coefficients are also non-zero. The final formula for the magnetic susceptibility resembles the case of the narrow multiplets for mononuclear systems spin-orbit coupling can be formally substituted by spin-spin (exchange) coupling. However, the local atomic g-tensors should be properly combined into the molecular-state g-tensor. [Pg.698]
