- Dielectric function of polyacetyleneLee, T. K.; Kivelson, S. (American Physical Society, 1984-06)The 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.
