Notes:
Multiconfiguration (MC) SCF calculations are reported for CO2 for bond angles between 60° and 180°. The ground state configuration is found to be …5a124b22∣b12∣a22 for small bending angles and …6a123b22∣b12∣a22 for large bending angles, the change in ground state character occurring at a bond angle of about 100°. The force constant for bending obtained from the MC-SCF function is about 8.0% lower than the corresponding SCF value, and in considerably better agreement with experiment.
