Abstract

In this study we determine gas temperature of He+H ₂, Ar+H ₂ and Ne+H ₂ high frequency electrodeless lamps using intensity distribution in rotational spectra of hydrogen molecule and hydroxyl radical. The measurement results show that OH rotational spectra can be successfully used for estimation of gas temperature of the high-frequency electrodeless lamps at very small amounts of hydrogen present in plasma. The analysis of the measurement results leads to the conclusion that in "pure" plasma the applied energy is used to heat plasma, while for the plasma with hydrogen addition the energy is used in chemical reactions.
