Interactions between Ground-State Nitrogen Atoms and Molecules. The N–N, N–N2, and N2–N2 Interactions

Abstract

Potential energy curves for N–N interactions corresponding to the X¹Σ_g⁺, A³Σ_u⁺, ⁵Σ_g⁺, ⁷Σ_u⁺, B³II_g, C³II_u, and a¹II_g states of N₂ have been calculated, as well as curves for the N–N₂ and N₂–N₂ interactions. All calculations have been based as nearly as possible on experimental data, including spectroscopically determined vibrational energy levels, scattering cross sections of atomic beams in gases, and measured vibrational relaxation times. In cases where experimental data were not available, approximate quantum‐mechanical calculations have been made. Results obtained by these various methods are remarkably consistent with one another, and are believed to have good accuracy.
