N2 - Laser-induced fluorescence of CO2+ (X̃ 2Πg) produced by electron impact on CO2 in a supersonic beam was measured. An analysis of the CO2+ (Ã-X̃) spectra has revealed that the rotational distribution of CO2+ is essentially Boltzmann and that the effective rotational temperature increases uniformly with decreasing impact energy, 26± 1 K at 300 eV and 31 ± 1 K at 45 eV. This trend of rotational excitation, which is similar to that observed in the N2 + e system, is interpreted in terms of the rotational transitions in electron-impact ionization.
