splitting in a magnetic field for the 2P 3>2, 2P 1>2, and 2S 1>2 energy levels for sodium, showing the anomalous Zeeman effect. These are the D 1 and D 2 lines in Figure 7-22. The splitting of the levels depends on L, S, and J, leading to more than the three lines seen in the normal effect. [Photo from H.E. White, Introduction to Atomic d-orbital diagram for [Fe(H 2 O) 6] 3+: The first three electrons go into t 2g orbitals unpaired. The 4th and 5th electrons must choose whether to pair up with electrons already in t 2g (which costs energy) or to go into higher energy e g orbitals (which also costs energy). In this case, the splitting energy is less than the pairing energy so the 4th and 5th electrons go into the e g orbitals.

The d orbital splitting diagram is shown in a box. Suppose the diagram above is for a first row transition metal. The diagram for a second or third row metal is similar, but with stronger bonds. If the bonding interaction is stronger between the metal and ligand, then so is the antibonding interaction. The antibonding levels are bumped higher ...

The d x2 - y2 and d z2 all point directly along the x, y, and z axes. They form an e g set. On the other hand, the lobes of the d xy, d xz, and d yz all line up in the quadrants, with no electron density on the axes. These three orbitals form the t 2g set.

But two of the d orbitals have lobes pointing along those axes - the 3d x 2 - y 2 and 3d z 2 orbitals. Those will feel more repulsion than the other three, which have lobes in between the axes. That means that two of the d orbitals will now have a higher energy than the other three - which is exactly what the diagram we have been using shows.
