Abstract

The Raman active normal modes of polyacetylene are described in terms of amplitude modes associated with the Peierls gap. A narrow distribution in the effective electron-phonon coupling constant accounts for the spectrum and its dependence on laser frequency. The resonant Raman condition determines a functional dependence of the gap on the coupling constant which is consistent with the Peierls relation. All infrared phonons induced by either doping or photogeneration are determined by the Raman data and a pinning parameter.
