Abstract
High resolution absorption spectra of the (4, 20) band in the second negative system (A2Î u-X2Î g) of O2+ cation were measured and analyzed in the range of 11Â 900-12Â 300Â 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.
