Using spectroscopic measurements vibrational and rotational temperatures were determined in the "ferroelectric" plasma source for different gas mixtures. It was shown that in this time-periodical, atmospheric pressure non-equilibrium discharge, both plasma temperatures differ strongly, and that the vibrational temperature is much higher (≈ 3 kK) than the rotational one (< 1 kK).

Using spectroscopic and electric measurements, vibrational and rotational molecular gas temperatures as well as free electron temperature and concentration were determined in different regions of a time-periodical type, atmospheric pressure non-equilibrium low current gliding arc. It was shown that this discharge includes an initial quasi-equilibrium zone, with the quasi-equilibrium temperature of 4 to 6 kK, and the non-equilibrium zone with the electron temperature about 10 kK, the vibrational temperature about 3 kK, rotational and translational temperatures from 1 to 1.5 kK. The transition between two mentioned zones coincides with the phenomenon of the arc "length explosion" already observed in moderate-current gliding arc.
