The dipole-dipole interactions of monomers with their images can result in strong {re-structuring of both the exciton band and the absorption spectrum, depending on the arrangement of the monomer transition dipoles with respect to the surface.4 two-column pages, Proceedings of the 8th International Conference on Excitonic Processes in Condensed Matter, June 22-27, Kyoto, JapanMaterials ScienceDisordered Systems and Neural Networkstext
