What is The role of solitons in the first Bu excited state of polyene chains: From short polyenes to polyacetylene about?
We present calculations on the geometry of the first 'B. excited state in polyene chains ranging in length from 5 to 29 double bonds. Calculations are performed in the framework of a Hiickel Hamiltonian with bond-length-dependent transfer integrals and with o-bond compressibility and use the parameters originally chosen for polyacetylene. Our results indicate that there is a smooth evolution of the 'B, excited state geometry relaxation on going from short to long chains. In all cases, we find that the 'B, excited state geometry tends to relax in such a way as 10 produce a pair of soliton defects. The implications of our results for the nonlinear optical properties of polyenes are discussed.
