| Abstract | The effects of interchain coupling have been studied on the localized vibrational modes around a soliton in doped and photoexcited samples of trans-(CH)(x) by using an extension of the SSH model in which two neighboring chains modeled individually by SSH Hamiltonian and coupled by an interchain electronic transfer term are considered. The electronic pinning: is also included within this model. The localized modes obtained in the SSH model are split and their frequencies are shifted after turning on the interchain coupling. Furthermore, our result can account for the three strong infrared lines at 900, 1260 and 1370 cm(-1) along with a weaker peak at 1150 cm(-1) in the optical absorption spectra of lightly doped samples. |
