    Abstract

    Spectra of the emitted light from an AC discharge formed on an ice surface were studied using a triggered spectrometer. It was observed that the recorded spectra contain OH (A-X) transition due to the presence of water molecules. In the later stages of discharge propagation while the arc current increases, this dominant transition is replaced by the spectral band of the first negative system (FNS) of N2+. Rotational temperature measurement was carried out by matching the measured spectrum of OH band with computer-simulated synthetic spectra.
