During the last decade, a huge number of exoplanets were discovered. Some of their atmospheres seems be so-called prebiotic and thus synthesis of molecular life precursors is probable. This synthesis can be initiated by radiation, star winds, volcanism or by lightning, i.e. electrical discharges. The aim of the PhD study is experimental observation of life precursors synthesis initiated by different electrical discharges generated in prebiotic atmospheres with various compositions. Experimental system will be operating at atmospheric pressure in the flowing regime. The temperature dependence of processes will be observed, too. Electrical discharges will be observed by optical emission spectrometry and by electrical measurements. The gaseous products will be determined by in situ proton transfer reaction mass spectrometry and Fourier transform infrared spectrometry; other techniques will be used partially, only. Whole study will be under the frame of Europlanet research network.
