[Measurement of N2+ rotational temperature in air dielectric barrier discharge]
The rotational lines of the first negative band system of N2+ were observed in air dielectric barrier discharge by using liquid electrodes. The rotational temperature was estimated by the J number of the lines with the maximum intensity in rotational spectrum. The rotational temperature was kept at a constant with increasing the applied voltage when the gas pressure was in the range of 10.133-60.795 kPa. The results are of great importance to the model foundation and the application of dielectric barrier discharge in air.
