Preliminary Examination of Crystals by Optical and X-ray Methods

Abstract

The optical examination of crystals is interesting in its own right. However, in structure determinations with modern equipment, it is not uncommon to proceed immediately with x-ray studies. In many cases, the technique is straightforward, particularly with the single-crystal x-ray diffractometer (Section 3.7), and the desired results are readily obtained. There are other situations though, where complications arise because of an unusual habit (page 126)—pseudosymmetry (page 312) or twinning (page 176). In such cases, it may be possible to extract useful information from an optical examination of a crystal before using the more detailed x-ray methods.
