摘要

总散射及其傅里叶变换，即对分布函数在晶体学中的重要性，在晶体能衍射x射线后不久就得到了认识。然而，在接下来的50年左右的时间里，其他更牢固地基于晶格的技术出现了，全散射测量主要是研究液体和非晶态结构的领域。在20世纪80年代后期，它被“重新发现”为一种揭示晶体结构内部无序的方法，从那时起，改进的仪器和分析的结合导致了全散射法的复兴。这篇综述列出了这段旅程，强调了早期的起源，更重要的是，总散射和对分布函数在今天的晶体学中经常使用的方法。

Total scattering and the pair distribution function in crystallography

The importance of total scattering and its Fourier transform, the pair distribution function, in crystallography was understood soon after it was shown that crystals diffract X-rays. However for the next fifty years or so other techniques based more firmly on the crystal lattice came to the fore and total scattering measurements were largely the domain of those studying liquid and amorphous structure. In the late 1980s it was ‘rediscovered’ as a way to uncover disorder within crystal structures and since then the combination of improved instrumentation and analysis has led to a resurgence of the total scattering method. This review sets out this journey, highlighting both the early origins and – more importantly – the ways that total scattering and pair distribution functions are routinely used within crystallography today.

期刊介绍： Crystallography Reviews publishes English language reviews on topics in crystallography and crystal growth, covering all theoretical and applied aspects of biological, chemical, industrial, mineralogical and physical crystallography. The intended readership is the crystallographic community at large, as well as scientists working in related fields of interest. It is hoped that the articles will be accessible to all these, and not just specialists in each topic. Full reviews are typically 20 to 80 journal pages long with hundreds of references and the journal also welcomes shorter topical, book, historical, evaluation, biographical, data and key issues reviews.
