DETERMINATION OF ROTATIONAL AND VIBRATIONAL TEMPERATURES IN A DISCHARGE WITH LIQUID NONMETALLIC ELECTRODES IN AIR AT ATMOSPHERIC-PRESSURE

Rotational and vibrational temperatures are measured by optical emissi on spectroscopy in a discharge with liquid non-metallic electrodes (DL NME) in air at atmospheric pressure. We used the transition Delta v = -2 of the second positive system of N-2 to determine the two parameter s of this discharge. In this paper we describe first the experimental set-up and then the method of determination of rotational and vibratio nal temperatures by comparison with calculated spectra. We present the results obtained along the discharge's axis.
