Theoretical and numerical simulations of inelastic light scattering by dielectric microspheres (sizes about 5–15 μm) irradiated with laser light of angular frequency ω 0 are presented. Applying a superposition of induced dipoles inside the particle volume, the so‐called morphology‐dependent resonances (MDRs) in Raman spectra are calculated. © 1997 John Wiley & Sons, Ltd.
