Abstract:The first and second moments of Raman scattered light on an ensemble of moving microparticles suspended in a gas are calculated. The theoretical predictions are verified by experiments. The relative measurement of the number concentration of individual particle classes is demonstrated as well as the determination of the degree of mixedness of the aerosol by exploiting the effect of this quantities on the moments and the frequency distribution of the detector signal.
