Abstract
Rotational temperatures were calculated versus current variation during dc discharge propagation on an ice surface. Strong diatomic molecular band of OH, N2+ 1st negative system and NH were observed from the captured spectra. In order to determine the rotational temperature, an optical emission spectroscopy (OES) analysis was carried out using the OH A-X (0, 0) transition band. Also, the rotational temperature was evaluated using the N2+ 1st negative system.
