Spin-polarized atomic nitrogen and the 7Σ+u state of N2

Abstract
We present the first self‐consistent field (SCF) calculation of the repulsive 7Σ+u state of molecular nitrogen. This calculation is used with attractive dispersion to provide a model potential for electron spin‐polarized atomic nitrogen N↑ appropriate in the range 2.5≤R≤20a0. Potential parameters obtained from the calculation are used to provide estimates of equilbrium thermodynamic properties of N↑ in the quantum theorem of corresponding states framework. Consideration is given to increased stability of N↑ with respect to single electron spin‐flip processes, as compared to H↑.
