| Abstract: | Autoionization states of O2 leading to the b 4Σg-, B 2Σg- and c 4Σu- states of O+2 have been well established, while those leading to the a 4∏u and A 2∏u are not certain. Further, some of the assignments of the autoionization states and the determinations of effective quantum numbers and quantum defects are open to questions. In view of a recent study of isotopic oxygen molecules, the vibrational assignments for the autoionization states leading to the a 4∏u and A 2∏ucan be unamiguosly assigned. We have systematically examined the known Rydberg series and have suggested new assignments and interpretations for several autoionization states leading to the various states of O2+. |
