It is well known that in a gas discharge plasma in mixture of CO{sub 2} with inert gas (Ar), a molecular carbon formation process occurs, characterised by the Swan band C{sub 2}(d{sup 3}{pi}{sub g}) {r_arrow} C{sub 2}(a{sup 3}{pi}{sub u}), located in the visible region of the spectrum. The rotational structure of this band of C{sub 2} is studied to determine the rotational temperature which can be approximated to the heavy particles temperature. The temperature determination is based on the comparison of experimental spectrum obtained by optical emission spectroscopy and synthetic spectra calculated for different temperatures.
