An ab initio molecular treatment of the charge transfer process in collision of C2+ ions with the isoelectronic CO and N2 targets has been performed. The corresponding rate coefficients in the 400–50000K temperature range are compared to recent measurements of Gao and Kwong at Tequiv=1.17×104K. A global satisfactory agreement is observed and some general behaviour may be deduced. [Display omitted] ► Calculation of rate coefficients for charge transfer processes between C2+ ions and the two isoelectronic molecules CO and N2 using ab initio calculation of potential energy curves and couplings. ► Comparison with recent measurements with cylindrical radiofrequency ion trap. ► Interest of this approach for the study of series of collision processes, in particular with molecular targets, diatomic or polyatomic molecules.
