[交流] 【求助完毕】翻译一段话(10月31日)

俄罗斯科学家D.Yu.Paraschuk在研究长链多烯类样品(Trans-Nanopolyacetylene)时,发现了由含有π电子共轭双键的多烯类长链分子,在分子结构有序时其光学性质发生很大变化,即拉曼活性增加(包括拉曼散射截面增加、非线性系数增加,紫外-可见吸收光谱变陡等光谱特性。)他提出了一个定性物理模型给予了解释,即“相干弱阻尼电子-晶格振动模型”。这一模型对线性多烯类分子的光学现象给予了科学的解释,受到相关研究人员的赞同。

In the study long chain alkenes sample (Trans-Nanopolyacetylene), Russian scientists D.Yu.Paraschuk found that the π-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.
