Soot volume fraction (fv) measurements are central to
studies of soot growth and radiant transport processes
within flames. In the post-flame region, soot yield and
specific extinction coefficient per unit mass of fuel
consumed in addition to fv are key quantities of
interest. Light extinction is widely used for measuring
these quantities but possesses limitations.
Interpretation of extinction measurements to determine
fv or soot yields rely on assumptions and uncertainities
regarding soot properties. Varying experimental
conditions can affect the contributions to the
extinction measurement of absorption by PAH's and
scattering, hence these contributions are often
