The rovibronic levels of the X2A1 and A2B2 electronic states of O3+ have been calculated variationally for the first time, using high-level (ICMRCI/cc-pcV5Z) ab initio diabatic potential energy surfaces which explicitly consider the non-adiabatic interaction between the two states. Vibronic levels for J = 1/2, 3/2 have been calculated and assigned for energies up to 2000 cm-1 above the ground state, making comparisons with recent results from ZEKE photoelectron experiments of ozone. The procedure has good predictive capabilities and it is used to confirm previous assignments and to tentatively identify some unassigned features in the low energy part of the O3+ spectrum.

Abstract

The rovibronic levels of the X2A1 and A2B2 electronic states of O3+ have been calculated variationally for the first time, using high-level (ICMRCI/cc-pcV5Z) ab initio diabatic potential energy surfaces which explicitly consider the non-adiabatic interaction between the two states. Vibronic levels for J = 1/2, 3/2 have been calculated and assigned for energies up to 2000 cm-1 above the ground state, making comparisons with recent results from ZEKE photoelectron experiments of ozone. The procedure has good predictive capabilities and it is used to confirm previous assignments and to tentatively identify some unassigned features in the low energy part of the O3+ spectrum.
