... for d2 using the methods applied earlier to p2, etc. They are 3F, 1D, 3P, 1G, 1S. We identify the GS as 3F. How? We saw earlier that F in octahedral environment splits to A2g + T1g + T2g; in tetrahedral we would get A2 + T1 + T2. Our problem is the energy ordering. Which is GS? Thus the 3F GS for d2 ...
