Abstract

An experiment suitable for studying the carbon molecular structures which are the candidates for carriers of the diffuse interstellar bands (DIBs) in astrophysical spectra has been developed in the plasma-chemistry laboratory of the Masaryk University in Brno. The experimental arrangement including an apparatus for detecting the gas phase spectra of monopolar high-frequency discharge is described. The preliminary results involving a search for the ultraviolet, visible, and near-infrared well pronounced features of the carbon molecular structures are discussed.
