If all of the eg orbitals are filled, can an electron from the t2g level be promoted to the
eg level by the absorption of a photon of visible light?
Draw the crystal field splitting diagram for octahedral Zn2+ and Ca2+ complexes. Predict the color of aqueous solutions of Zn2+ sas and Ca2+ sas. Does it matter if the complexes are high-spin or low-spin?
