BOND-BENDING EFFECT ON LOCALIZED VIBRATIONS OF SOLITON FOR TRANS-(CH)x
聚乙炔孤子的二维局域振动模及其键弯曲势的影响

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.
