Consider the linkage isomerization Cr3+-CN-Fe2+ — Cr3+-NC-Fe2+ described in the text. Show by using ligand field theory (magnitudes of Dq) that this process should be energetically favorable. 

There have been several attempts to provide a theoretical framework for describing geometrical isomerization and racemization. Vanquickenbome and Pierloot used ligand field theory to calculate the electronic energies of the intermediates pr osed in the dissociative and trigonal twist mechanisms for low-spin d systems.
