Abstract The luminescence intensity profiles of Lyman–Birge–Hopfield bands of molecular nitrogen have been calculated for the precipitation into the Earth’s atmosphere of electrons with energies of 10 keV to 10 MeV. With an increase in the energy of electrons penetrating the atmosphere, there is an increase in the contribution of the quenching of the a 1 Π g N 2 state in molecular collisions. This leads to a reduced ratio of the integral luminescence intensities of the Lyman–Birge–Hopfield ultraviolet bands and the second positive system upon an energy increase in high-energy electrons precipitating into the atmosphere.
