We study the lattice vibrations of soliton in two-dimensional model and find that the vibrational amblitudes of carbon atoms normal to chain is comparable to that along the chain for most of the modes. Compared with the results of SSH model, a number of new modes have been found. They depend on the coupling constant and the bond-bending.
