1) Fill the following table for octahedral complexes. Refer to your class notes and the Tanabe-Sugano diagrams (Figure 11-7).

* If there is more than one allowed transition, list them in order of increasing energy.
2) Fill the above table but now for tetrahedral complexes (all HS).
3) Practice filling the above table but use real octahedral and tetrahedral complexes from among those given in the problems for the Exam II material you were handed out.
