An in situ chemical and physical characterization of soot particles during the separate stages of formation and oxidation appears to be an important step forward in the understanding of the heterogeneous aspects of the kinetics. To this end the knowledge of the optical properties of soot particles inside rich flames is of great relevance and categorizes soot among the large family of carbonaceous materials. This article proposes a new method for the evaluation of the dispersion of the optical properties of absorbing submicronic aerosols, starting from the simultaneous measurements of the scattering and extinction coefficients in the near UV and visible.
