摘要：

The effect of branch points and site impurities on a conjugated trans-polyacetylene chain is studied using minimum energy calculations performed directly on the Su-Schrieffer-Heeger Hamiltonian. New mid-gap states found in the case of branched molecules are described. The evolution of nonlinear excitations as a site potential is turned on is investigated.
