Abstract

When molecules which give rise to Raman and fluorescent light scattering are distributed within a small dielectric particle, the signal is affected by the morphology and optical properties of the particle and by the distribution of active molecules within it. This effect is considered to arise from the influence of the particle boundary both upon the internal field at the incident frequency and upon the emissions at the shifted frequency rather than from any alteration of the molecular transitions. This study presents numerical results over a broad range of refractive indexes and for larger size parameters than heretofore. It includes explicit consideration of components polarized in the same plane as the incident field, H_h and V_v, as well as the depolarized components V_h and H_v. Quantitative estimates of the concentration of active species may be in error if these effects are not considered.
