Electronic states distortion origin

The Jahn-Teller (JT) effect occurs in the presence of degenerate electronic states. A spontaneous distortion of the lattice (or here of the C60 molecule) would lift the degeneracy between these states, if it reduces the symmetry at the origin of the degeneracy. If these levels are only partially occupied, the electrons occupy the... [Pg.166]

A number of the distortions found in cation coordination environments are the result of electronic instabilities in the atoms themselves. Such distortions are typically found among the transition metal cations and the main group elements in low oxidation states. The origins of these instabilities are different and they... [Pg.47]
