1. Consider in more detail the lowest energy transition of a d6 ion in a weak ligand field.

a) (i) Give the symmetry designations and strong field configurations for the ground and excited states [something like 4A1g(t2gxegy) → 4Eg(t2gmegn)].(ii) Draw the d orbitals splitting diagram for an octahedral complex with the electrons included for both the ground and excited state from a(i) above. (iii) What is the energy difference between the two strong-field configurations?

(b) Do these two states come from the same free ion term? Would you therefore expect them to have the same or different electron-electron repulsion?

(c) Using the Tanabe-Sugano diagram, give the energy of this transition (E) in units of B when Δo = 10 B. Give the energy of the transition when Δo = 20 B.

(d) Combining your answers to (a)-(c), give the very simple mathematical equation that relates E and Δo for this transition.
