Апстракт
This paper summarizes theoretical investigations of changes in optical properties of smallest symmetrical nanofilm-molecular crystals due to the presence of boundaries and different boundary parameters. Using analytic and numerical calculations, the energy spectrum of excitons was found and relative permittivity of these ultrathin dielectric films was determined. The influence of boundary parameters on the occurrence of discrete (by parameters)and selective (by planes)absor ption of external electromagnetic radiation was also investigated. Because of the symmetric conditions on film boundaries, double resonant peaks appear.
