Non-degenerate orbitals

Jahn-TeHer effect The Jahn-Teller theorem states that, when any degenerate electronic slate contains a number of electrons such that the degenerate orbitals are not completely filled, the geometry of the species will change so as to produce non-degenerate orbitals. Particularly applied to transition metal compounds where the state is Cu(II)... 

Fig. 20.4. A schematic representation of some non-bonding and n -bonding molecular orbitals in SO3 or NO3. Left the three essentially non-bonding a molecular orbitals formed by linear combinations of oxygenp orbitals in the molecular plane. In SO3 these orbital are completely filled by six electrons, in NO3 the highest, non-degenerate orbital contains a single electron. Right the four n molecular orbitals formed by linear combination of the valence shell AOs of the four atoms.

In the presence of ligands a transition metal ion is not isolated. The co-ordinate bonding from the ligands causes the five d orbitals in the transition metal ion to split into two sets of non-degenerate orbitals at slightly different energy levels (Figure 24.14). In a complex with six...
