The molecules and molecular clusters of high symmetry with orbital degeneracy of the ground state are unstable with respect to a weak structural deformation due to Jahn-Teller effect. In the Sect. 7.1 is discussed the possibility for existence of an analogical effect of instability of spin populations of the trihomonuclear magnetic cluster with respect to a weak structural deformation (the Kahn’s instability) in the case when each of three ions of the cluster has the spin \(S=1/2\).
