Potentials of internuclear interaction of diatomic molecules in planetary atmosphere

A method is given for the calculation of Ridberg–Klein–Rees potentials (RKR potentials) of internuclear interaction of diatomic molecules, which is based on a combination of numerical and analytical computer codes. A calculation of potentials of internuclear interaction is performed for $32$ electron states of $\mathrm{N}_2$, $\mathrm{N}_2^+$, $\mathrm{C}_2$, $\mathrm{CO}$, $\mathrm{CO}^+$ and $\mathrm{CN}$ molecules of practical interest as regards problems in aerophysics of interplanetary space vehicles. Complete spectral information is given for the calculation of potential curves, which may be used for unique comparison of the results of calculations of internuclear potentials obtained by different methods.
