The Study of the Kinetics of the Triplet States B3Πg and C3Πu of Molecular Nitrogen at Air Pressures of 0.03–1 Torr
The kinetics of triplet states of molecular nitrogen and the emission of bands of the first positive system (1PG) and second positive system (2PG) were studied for air pressures at which red sprites are observed. The spectral energy densities W of the emission of six 1PG bands and three 2PG bands were measured experimentally in a pulsed discharge with plasma diffuse jets at pressures of 0.03–1 Torr. The populations of various vibrational levels of the triplet states of molecular nitrogen and the spectral energy density ratios W1PG/W2PG were calculated in the pressure range considered. Good agreement was obtained between the calculated and experimental values of the W1PG/W2PG ratio. The spectral energy density ratio W1PG/W2PG was shown to decrease with increasing pressure, which is explained by a rise of the quenching rates of the B3Πg state with increasing density of the medium.
