Abstract: An unusual behavior was observed for the spontaneous Raman spectra in the range of the passband of $trans$-poly(acetylene) nanoparticles. The following phenomena are observed for the stretching carbon-carbon vibrations: large scattering cross section; high anti-Stokes-to-Stokes ratio; no correlation between the absorption spectra of $trans$-nanopoly(acetylene) and the Raman excitation spectrum. A qualitative model is proposed for synchronous weakly damping electron-nuclear vibrations in the ordered poly(acetylene) chain.
