We report on the application of Optical-Optical Double Resonance (OODR)LIF to the detection of N2(A3Σ u + in a dielectric barrier discharge (DBD) along two research lines. At low pressure (1 ÷ 30 Torr) OODR-LIF is used to selectively excite N2(C3Πu, v = 1) and obtain, with a direct method, electronic quenching and, for the first time, the collisional vibrational relaxation rate coefficient (C, v = 1) → (C, v = 0). At high pressure OODR-LIF is used to measure, again for the first time, N2(A3Σ u + density with time and space resolution in an atmospheric pressure DBD, with the aid of a spectroscopic calibration method that relies upon the measurement of SPS and NO-γ emissions in the post-discharge.
