摘要：

The geometrical structures of linear chain systems are shown to be sensitively reflected on the optical spectrum of Frenkel and Wannier excitons. The effects of shape of the chain on the Frenkel exciton absorption spectrum are represented by the geometrical factor describing the global chain structure and the line broadening due to the structure fluctuations. The corner with the stronger curvature induces the stronger attractive potential on the Wannier exciton so that the bound states are formed.
