B 29, 6687 DOI: http://dx.doi.org/10.1103/PhysRevB.29.66871098-0121http://hdl.handle.net/10919/47824The optical dielectric function for polyacetylene has been calculated in the random-phase approximation. Local-field corrections are included. The optical-absorption coefficient obtained is in good agreement with experimental data. The contributions of interchain coupling and exchange interaction are discussed.en-USIn Copyrightphysics, condensed matterArticle - Refereedhttp://journals.aps.org/prb/abstract/10.1103/PhysRevB.29.6687https://doi.org/10.1103/PhysRevB.29.6687
