Abstract

High resolution absorption spectra of the (4, 20) band in the second negative system (A²Π_u-X²Π_g) of O₂⁺ cation were measured and analyzed in the range of 11 900-12 300 cm^-1 via optical heterodyne velocity modulation spectroscopy. Precise molecular constants of the levels involved were obtained by a nonlinear least-squares fitting procedure combining with our previous spectra of the (4, 19) and (6, 20) bands.
