Determination of rotational and vibrational temperatures in a discharge with liquid non-metallic electrodes in air at atmospheric pressure

摘要

Rotational and vibrational temperatures are measured by optical emission spectroscopy in a discharge with liquid non-metallic electrodes (DLNME) in air at atmospheric pressure. We used the transition Delta v = -2 of the second positive system of N-2 to determine the two parameters of this discharge. In this paper we describe first the experimental set-up and then the method of determination of rotational and vibrational temperatures by comparison with calculated spectra. We present the results obtained along the discharge's axis. [References: 12]
