Characteristic of the B2Σ+ and X2Σ+ states in the CO plus isotopic molecules

Two electronic states have been investigated on the basis the First Negative (B-2 Sigma(+) -> X-2 Sigma(+)) system observations in the emission spectrum of the (CO+)-C-12-O-16 and (CO+)-C-13-O-16 molecules. For this purpose the conventional technique of hight resolution spectroscopy has been implemented. Thirty eight bands, belonging to this system, were recorded in the both isotopic species. The reduction of the spectrum for the individual bands has been performed via a nonlinear least-squares fit with the effective Hamiltonian of Brown. As a results of multistage and merged analysis of the currently obtained data and those obtained earlier, for the other systems, the state of information about energy structure CO+ molecule has been significantly enlarged.
