Abstract: We present an analytical theory of plasmons excited in spherical metal resonators filled with the molecules under study. A simple L‒C model of plasmons generated in a metal nanoshell is developed. The electromagnetic mechanism of surface-enhanced (giant) Raman scattering (SERS) can be investigated qualitatively and quantitatively. The theoretical results are in qualitative agreement with computer simulations. The results of the SERS experiment in polystyrene spheres coated with a silver nanolayer are presented.

Keywords: electric field enhancement, plasmon resonance, giant Raman scattering, metal microspheres, metal microspheres.
