The structural change in the cis-polyacetylene photoexcited with the energy corresponding to its band gap was examined. The growth of four new infrared absorption peaks at 802, 1062, 1112 and 1259 cm-1 were found after the irradiation. The appearance of these peaks strongly suggests the formation of the trans-cisoid segment in the cis-transoid chain of polyacetylene.
