Estimation of the plasma temperature by using the resolved spectrum of N₂⁺

Instytut Fizyki, Uniwersytet Opolski, ul. Oleska 42, Opole, Poland

Abstract

This publication analyzes the problems of estimating the gas temperatures in the nitrogen-containing plasma in the temperature regions between 4 and 9 kK. Problems of low and high resolution molecule bands spectroscopy and temperature derivation is discussed and the proposition of the quick procedure is presented. Its validity is tested by comparison of the temperatures derived from different molecular bands by the help of the Boltzmann rotational structure diagrams. The perturbation in the molecular spectrum is exploited to choose the most easily resolved spectral lines.
