• Solitons (localized objects) in cis-polyacetylene are examined by bosonizationof electron operators and semiclassical treatmernt of the bosonjzed operators,where some parts of Coulomb interactions are taken into account. There arethree types of soliton solutions ; a polaron, a charge bisoliton and a spin bisoliton.Among them an isolated polaron seems to be stable in a doped substance. Cis-trans isomerization by doping is described in terms of such solitons. The regionbetween dopants sufficiently close isomerizes ; the largest dopant distance toisomerize is about 21 lattice spacings.
