Abstract:A detailed analysis of the population of the N2 vibrational states for the N2 (C 3 II u,X 1 Sgr g + ) electronic states has been carried out. Quantitative spectral and microwave measurements of vibrational temperatures and electron densities were performed for 2400 MHz non-isothermic pulsed discharges in flowing nitrogen at pressures (60–2700) Pa. From the time dependent peak intensities of the second positive system of N2, the temperature of neutral gas during the h.f. pulses has been determined.
