FIG. 2.
Canonical valence orbitals of the state-averaged CASSCF(18,12)/cc-pVTZ wave functions for the 11A1 and 21A1 states of O3 at the OM and RM. Between the orbitals of each pair, the symmetry label (in C2v) is given. Below each orbital, the orbital occupations in the 11A1 state and in the 21A1 state, as well as the canonical orbital energy are listed, in that order.
