有关绝对结构和绝对配置的基本概念，并从单晶衍射测量确定，提出和审查。提供了一个术语表，其中包括在这一领域有用的定义。对于绝对结构及其确定，单独的，但相互作用的影响的结构和反转区分能力的X射线衍射实验与色散散射体进行检查。提供了用于绝对结构测定的当前方法的重要实验和算法细节。表征晶体的绝对结构确定和分子的绝对配置确定处理。着重分析了孪晶的绝对结构和绝对位形。
Fundamental notions concerning absolute structure and absolute configuration, and their determination from single-crystal diffraction measurements, are presented and reviewed. A glossary of terms with definitions useful in this field is provided. For absolute structure and its determination, the separate but interacting influences of the structure and the inversion-distinguishing power of an X-ray diffraction experiment with dispersive scatterers are examined. Important experimental and algorithmic details of the current methods used for absolute-structure determination are provided. Characterization of crystals for absolute-structure determination and of molecules for absolute-configuration determination are treated. Attention is given to the analysis of absolute structure and absolute configuration in twinned crystals.
