The experimental and theoretical curves of radial temperature distribution of the arc burning in carbon dioxide, compared with corresponding curves in nitrogen, are considered. The theoretical curves are obtained by solving Elenbaas-Heller, energy balance equation according to Maecker. The model of the freely burning arc, under conditions usually applied in spectrochemical practice is used. Carbon dioxide exemplifies a plasma whose thermal conductivity as a function of temperature shows two maxima. In spite of one maximum being in approximately the same temperature interval as that of nitrogen, the presence of the second maximum causes the radial temperature distribution to become more abrupt in the luminous zone of the arc.
