Application of the (0,0) Swan band spectrum for temperature measurements

Emission spectra of the 516.611 nm Swan band of the molecule were employed for evaluation of the rotational temperature in different plasma sources. This diagnostic method may be applied in the temperature range from 300 - 6000 K and is especially useful for noisy and spectrally not well-resolved spectra when the apparatus function of a recording system is unknown. The described method is based on a comparison of experimental data with the theoretically calculated spectrum. The numerical minimization procedure is started with the temperature value obtained from the Boltzmann plot or the intensity ratio of two selected spectrum components. An analysis of a theoretically calculated spectrum is presented. Two plasma sources were examined, a plasma torch recombining jet and high-voltage-triggered dielectric barrier discharge (DBD).
