Paper Abstract

High-resolution infrared spectroscopy of molecular ions and free radicals has witnessed a dramatic progress in the past ten years. Spectroscopic identification and characterization of transient species are of great importance for understanding elementary processes in discharge plasmas. Infrared spectroscopy of molecular ions is a relatively new field. Nevertheless, up to the present time, more than 50 species (including negative ions) have been identified and the spectroscopic constants have been determined. In this presentation, some of the more recent results are reviewed, and a new observation of the infrared spectra of D3 and formation mechanism of triatomic hydrogen radicals in hydrogen discharge plasma are discussed.
