Abstract
In this paper we investigate the possibility to apply the concepts of non-specific intermolecular interactions and dispersive local field effect approach for study of the influence of interactions of metal nanoparticles with matrix molecules on the spectral characteristics of composites. The effect of intermolecular (interparticle) interactions and the influence of the dielectric environment on the peak position of the plasmon resonance band of colloidal solutions and thin films formed from noble metal nanostructures is determined. Simulated and experimental absorption spectra obtained for a colloidal solution of silver and gold nanoparticles, of various shapes and sizes in water and glycerol, are in good agreement.
