| 众所周知，分子的光谱特性与分子结构、状态、密度相关。多烯类链状分子番茄红素、β-胡萝卜素随在CS2中浓度变化，吸收光谱、拉曼散射光谱发生变化，显然是随浓度变化番茄红素、β-胡萝卜素分子结构状态发生变化所致。 |

| It is well known that the spectrum properties of a molecule is associated with its molecular structure, condition and density. With their different concentrations in CS2, the absorption and Raman scattering spectra of some polyene chain molecules such as lycopene, carotene will vary, which apparently results from the changes of their structures and condtions with differing concentrations. |

| It is popularly accepted /well-known that the spectrum properties of a molecule are closely related to its sturcture, state and density. The absorption spectrum and Raman scattering spectrum of 多烯类链状分子番茄红素、β-胡萝卜素 change aong with its concentration change in CS2, obviously due to their changes of structure and state. |

It is well known that the spectrum properties of molecule are associated with the molecular structure, status and density. It is obvious that the change of the absorption spectrum and Raman scattering spectrum is along with the change of lycopene and carotene structure which is effect by the various concentrations in CS2. 好费劲 |
