Abstract
The characteristic intensity distribution in the N2 second positive bands observed in high-temperature air plasmas generated by a micro-air plasma-jet generator was reconstructed by the theoretical spectra with predissociation and non-Boltzmann rotational population distribution. In order to construct the precise theoretical spectra, collisional transition rate coefficient that was applicable at high temperatures was proposed based upon a simple collision theory. In addition, the effect of the radiative transition from C3Πu to B3Πg state was included in the master equation. The theoretical spectra with non-Boltzmann rotational population distribution calculated with such factors agreed very well with the experimental ones.
