Notes. Thesymmetries leading to covalent-ionic interactions among the considered states, and thus which need to be calculated, are shown at the bottom along with their statistical weights. For covalent configurations where oxygen is neutral and/or hydrogen is in the ground state, this information is implied and omitted for clarity.
