Quasi-elastic light scattering spectroscopy is a non-invasive technique for measuring the motion of molecules and macromolecules in transparent liquids, solids, and gases. By illuminating a scattering sample with a laser beam, and studying the temporal evolution of the continued fluctuations in the intensity of the scattered light, one may in particular cases infer translational and rotational diffusion coefficients, sound speeds, thermal conductivities and other molecular parameters of the sample. Because of its wide range of applications, most recent conferences have emphasized light scattering spectroscopy in relation to particular topics (e.g. colloids aerosols, rheology, polyelectroytes) as opposed to emphasizing the common themes of spectral observation and interpretation which run through all of these applications. Indeed, because of the wide range of disciplines in which light scattering techniques have been applied, conferences sponsored by a single professional society will of necessity focus on particular systems to which the technique can be applied, without considering in a general way the underlying principles and methodology. Support is therefore herein requested for a conference of light scattering spectroscopists - to include workers in the fields of chemistry, pharmacology, medicine, biology, chemical engineering, and physics - to discuss recent work on light scattering techniques. A major focus of the conference will be the types of problems encountered in the study of biochemical systems, such as the complex spectra exhibited by biopolymer mixtures, as well as new sorts of solutions for this problem such as optical labeling techniques and light scattering electrophoresis.

准弹性光散射光谱是一种非侵入性技术 测量透明介质中分子和大分子的运动 液体、固体和气体。 通过用光照射散射样品 激光束，并研究持续的时间演化 散射光强度的波动，尤其是 案例推断平移和旋转扩散系数、声音 速度、热导率和其他分子参数 样本。 由于其应用范围广泛，最近的会议 强调了与特定相关的光散射光谱 主题（例如胶体气溶胶、流变学、聚电解质）而不是 强调光谱观测和解释的共同主题 它贯穿所有这些应用程序。 确实，因为宽 光散射技术已被应用的学科范围 应用，由单一专业协会主办的会议将 有必要关注该技术可以应用的特定系统 应用，而不以一般方式考虑基本原则和 方法论。 因此，在此请求支持召开一次会议 光散射光谱学家 - 包括以下领域的工人 化学、药理学、医学、生物学、化学工程等 物理学 - 讨论光散射技术的最新工作。 一个专业 会议的焦点将是在该领域遇到的问题类型 生化系统的研究，例如复杂的光谱 生物聚合物混合物，以及解决该问题的新型解决方案 例如光学标记技术和光散射电泳。
