Figure 11.25 The electronic ground state and a few excited states of a hypothetical molecule. Above, orbital energy-level diagrams specify symmetry properties and illustrate orbital occupancies for various states the molecular orbital set is the same for each state in this approximation. Below, the states are shown on an energy scale. Each state function is a product of orbital functions for the electrons, with state symmetry determined by multiplying the symmetries of the electrons (+1 for S, — 1 for A).
