- Аннотация: The mechanisms of the production of vibrationally excited NO and N 2 molecules at the altitudes of the middle atmosphere of the Earth during high‐energetic proton precipitation on January 20, 2005 are considered. The study of vibrational populations N 2 (X ¹ Σ g ⁺ , v '>0) during high‐energetic proton precipitation has shown different principal mechanisms in the N 2 (X ¹ Σ g ⁺ , v '>0) excitation. Firstly, the excitation by secondary electrons is principal for vibrational levels v '=1−10. Secondly, it is obtained that intramolecular electron energy transfer process in N 2 (A ³ Σ u ⁺ )+N 2 collisions dominates in vibrational excitation of high vibrational levels v '=20−30. It is shown that the chemical reaction of metastable atomic nitrogen with molecular oxygen is the main production mechanism of vibrationally excited NO(X ² Π, v >0) and of the radiation of 5.3 μm and 2.7 μm infrared emissions at these altitudes. The calculated intensities of the 5.3 μm emission are compared with experimental data from SABER instrument on TIMED spacecraft received at the time of the proton precipitation. The role of VV'‐processes in the radiation of 5.3 μm infrared emission is discussed.
