Abstract: The electronic states of a C_(60) molecule have been calculated by using the SSH model. The electronic energy spectrum and dimerization on molecular structure are in good agreement with that obtained from the method of molecular orbit and local density function theory. With the SSH model, there is string polaron for both neutral excited and charged C_(60) molecule, and this is consistent with the experimental results. Besides, a comparison has been made between C_(60) and polacetylene.
