外场对多原子气体输运性质的影响（“Senftleben-Beenakker效应”）和解偏振瑞利散射（“DPR”）是由分子间相互作用的非球形部分引起的。它们基于线性化玻尔兹曼方程的统一描述给出了这些实验的有效截面，即速度和旋转量子数的平均值。这些可以用于潜在模型的多属性分析。或者，它们也可用于通过利用截面之间的理论关系直接确定各种其他截面。本文介绍了SBE和DPR以及关于这些现象的大量文献。简要描述了实验技术，其可能性和局限性。各种气体的可用截面的概述有助于从文献中检索。
The effects of external fields on transport properties of polyatomic gases (‘Senftleben-Beenakker effects’) and Depolarized Rayleigh light scattering (‘DPR’) result from the non-spherical part of the intermolecular interaction. Their unified description based on the linearized Boltzmann equation gives the results of such experiments in terms of effective cross sections, which are averages over velocities and rotational quantum numbers. These can be used for a multiproperty analysis of potential models. Alternatively, they may be employed for determining various other cross sections directly by making use of theoretical relations between cross sections. This paper serves as an introduction to SBE and DPR and to the vast literature on these phenomena. A brief description is given of the experimental techniques, their possibilities and limitations. An overview of the available cross sections for various gases facilitates their retrieval from the literature.
