Abstract: The (5, 21) band in the A2Πu -X2Πg system of O2+ was studied for the first time, by employing optical heterodyne detected velocity modulation spectroscopy in the region of 11 387~11 800 cm-1. Adopting effective Hamiltonians, the precise molecular constants of the lower level involved were obtained by a nonlinear least-squares fitting procedure.

Key words: second negative system, molecular constants, O2+, second negative system, molecular constants
