摘要

简要介绍了光散射光谱技术在稀大分子溶液动力学性质研究中的应用。在这种类型的实验中,光被溶液中分子在平衡状态下的热波动所散射。在条件允许的情况下,光散射可以用于研究大分子在稀溶液中的平动扩散、旋转扩散、分子内结构弛豫过程和化学反应速率常数。

Light scattering spectra and dynamic properties of macromolecular solutions
A brief account of the applications of light scattering spectroscopy to the study of the dynamic properties of dilute macromolecular solutions is presented. In experiments of this type, light is scattered by thermal fluctuations of the molecules in solution about equilibrium. When the circumstances permit, light scattering may be used to study translational diffusion, rotational diffusion, intramolecular structural relaxation processes, and chemical reaction rate constants of macromolecules in dilute solution.
