Summary:The analytical theory as well as experimental observation of the plasmons excited in the spherical metal resonator stuffed by investigated molecules is presented. A simple lumped model of the plasmons generated in the metal nanosphere is developed. The electromagnetic mechanism of the surface-enhanced Raman Scattering (SERS) can be investigated qualitatively and quantitatively. The theoretical results are in a qualitative agreement with our experiment on SERS in silver coated polystyrene spheres.
