The ions that are expected to form colored octahedral complex ions are to be determined. Concept introduction: There is degeneracy in the d orbitals of a transition metal atom or ion. It means they have same energy levels. But when they interact with ligands, the d orbitals become non degenerate, i.e. they do not have same energy. Color of the complex ions depends upon how the 3d electrons occupy the split energy levels. To determine: If Zn +2 will form colored octahedral aqueous complex or not.

A molecule shows peaks at 1379, 1327, 1249, 739 cm-1. Draw a diagram of the energy levels for such a molecule. Draw arrows for the possible transitions that could occur for the molecule. In the diagram imagine exciting an electron, what are its various options for getting back to the ground state? What process would promote radiation less decay? What do you expect for the lifetime of an electron in the T1 state? Why is phosphorescence emission weak in most substances? What could you do to a sample to enhance the likelihood that phosphorescence would occur over radiationless decay?
