In consideration of the influence of a planar polythiophene configuration,we study the localized vibrational modes around an electronics bipolaron by using a two-dimensional SSH model.Fifteen lo-calized vibrational modes have been found,among them,four infrared active localized vibrational modes and four Raman active ones could be used to interpret the four observed intense infrared ab-sorption lines at 1020,1120,1200 and 1323 cm-1,and the four Raman active absorption peaks at 700,1047,1175 and 1220 cm-1,respectively.
