Laser-induced fluorescence (LIF) and single vibronic level (SVL) emission spectra of the ~A^2Π_u - ~X^2Π_g} system of 12CO_2^+ and 13CO_2^+ and the ~A^2Σ^+ - ~X^2Π system of N_2O^+ have been observed. The cations were produced in a pulsed electric discharge jet with a precursor mixture of the corresponding neutral molecule in high pressure argon. The LIF bands of 12CO_2^+ and 13CO_2^+ were partially rotationally analyzed to obtain band origins which yielded an accurate measure of the excited state vibronic energy levels. The energy levels of both isotopologues were fitted with a Renner-Teller model that included spin-orbit coupling, Fermi resonance and anharmonic terms. SVL emission spectra were also recorded for the 13CO_2^+ ion and the ground state energy levels fitted using the same Renner-Teller model. Due to excited state predissociation, only the low lying vibrational levels have been observed in the LIF spectrum of N_2O^+. Nitrous oxide cation SVL emission spectra were collected and a complete vibronic analysis of the ~X^2Π electronic state has been carried out using the Renner-Teller model. Our experimental data provide rigorous tests for future ab initio potential energy surfaces of these important cations.
