Concentrations of NO, NO 2 , NO 3 , N 2 O 5 , and O 3 were measured by classical absorption spectroscopy in dielectric barrier discharges in flowing O 2 /NO x and N 2 /O 2 /NO x mixtures. The results of measurements in different parts of the discharge chamber and in its exhaust are compared to a numerical zero-dimensional kinetic model and good agreement is found. The experimentally found upper limit of the NO x concentration allowing ozone production is confirmed by the kinetic calculations for both gas mixtures. The rotational temperature of different nitrogen bands was measured by high-resolution emission spectroscopy. The results are explained on the basis of a simplified model and related to the gas temperature in the microdischarge channel and the surrounding gas.
