Abstract The linear correlated constants AD (centrifugal correction of the spin-orbit coupling constant) and γ (the spin-rotation constant) involved in the second negative (A2Πu-X2Πg) system of O2+ are determined by nonlinear least-squares fitting the spectra of 16O2+ and 18O2+ using the isotopic effect. In addition, the molecular constants of the other O2+ isotopologues are predicted.
