RÉSUMÉ

Spectra in the range of 365−385 nm, corresponding to the Schumann-Runge system of O2 (B3Σu− X3Σg) and to the second positive system of N2 (C3Πu− B3Πg) are measured by optical emission spectroscopy in a discharge with liquid non-metallic electrodes (DLNME) in air with water at atmospheric pressure. They are simulated theoretically. This discharge generates a non-equilibrium plasma. In this paper, we first describe the experimental set up. Then, we explain the method of spectra simulation. By comparison of measured and simulated spectra, we determine the rotational and vibrational temperature and the ratio between densities of two upper electronic quantum levels of the two considered systems. The possible mechanism of spectra formation is discussed.
