Abstract
Abstract In this study, the NOγ (A2Σ+−X2Π) emissions from the high-voltage pulsed corona discharge in humid air at atmospheric pressure were successfully recorded. The (1, 0) and (0, 1) head bands of NOγ system was used to determine the vibrational temperature of NOγ, by simulating the experimental spectra with the aid of SPECAIR simulation software. The influences of applied voltage, frequency and hygrometry rate on the vibrational temperature of NOγ in humid air are investigated separately. It is found that the vibrational temperature rises linearly with increasing the applied voltage and the frequency but decrease with the increase of rate hygrometry.
