| In the study long chain alkenes sample (Trans-Nanopolyacetylene), Russian scientists D.Yu.Paraschuk found that the ¦Ð-conjugated double bonds in multiple vinyl long-chain molecules change drastically in the orderly molecular structure of the optical nature. Specifically, Raman activity increases, including the Raman scattering cross section, non-linear coefficient in UV - visible absorption spectra steepening spectral characteristics, etc.. He proposed a qualitative physics model to give an explanation based on "coherent weakly damped electron - lattice vibration model. " This linear optical phenomenon model of multi-vinyl molecules provides a scientific explanation, which has been endorsed by the researchers. |
