摘要：

It is shown that from the polarization properties of the infrared spectrum or oriented pristine trans polyacetylene evidence of Peierls distortion is obtained. It is shown that during CH stretching and in-plane bending CC bonds develop relevant charge fluxes. Infrared intensity studies indicate the existence of an unusual charge mobility.
