AB - In this article influence of variation of size of nanoparticles and interparticle distance on surface plasmon resonance spectrum of silver nanoparticles is studied. The conformity of measured spectrum of spontaneous periodic structures with simulation results was studied by investigation the ellipsoidal approximation limits. Our results shows that at distances less than 4r0 (r0 is radius of nanoparticle) we can approximate two spherical nanoparticles by an equivalent ellipsoidal nanoparticle, and at distances greater than 4r0 this approximation is not appropriate.
