Chapter 2.2, Problem 2.4E

A third possible state for the $p^4$ configuration would be $\underset{\_}{\uparrow \downarrow }\underset{\_}{\uparrow }\underset{\_}{\downarrow }$ Determine the Coulombicand exchange energies of this state, and compare its energy with the energies of the statesdetermined in the preceding example. Draw a sketch showing the relative energies of these threestates for oxygen’s $p^4$ configuration.
