Because of its low efficiency, spontaneous Raman scattering is still a rarely used method for analysis of reacting flows, especially if they are unsteady as turbulent combustion or pulse discharges. For this purpose, an experimental setup was developed, associated with specific analytical procedures. This setup was evaluated in two cases : a premixed flame and nanosecond discharge as a new ignition method. Measurements demonstrate the originality and the novelty of the results that can bring the spontaneous Raman scattering to the analysis of complex reacting flows. The discharge is generated in a point-plan gap of air and lean propane-air mixture by an application of a positive high voltage pulse of 25 KV and 25 ns to the point electrode a...
