Abstract

A hybrid modeling technique is reported for studying inelastic (Raman and fluorescent) scattering from molecules embedded in spherical particles of large optical size parameters. The modeling technique, which combines the Lorenz-Mie theory (for determination of the incident excitation field) with a geometric optics formulation (for determination of an inelastic-scattering efficiency function), permits predictions of a weighting function inside a particle and also the angular scattering patterns. These calculations provide insight into the scattering processes and may serve as a theoretical basis for guiding experiments and interpreting results in aerosol particle thermometry by using inelastic-scattering techniques.
