%X Based on the extended two-dimensional Su_Schrieffer_Heeger model of polythiophene, we have studied numerically the pinning effects of the Coulumb interaction o n the localized vibrational modes around a bipolaron in polythionphene. Some new localized vibrational modes are found. The numerical results are almost in good agreement with the results of optical absorption experiments.
