Abstract
In this chapter we shall discuss the interaction between crystals and two different electromagnetic radiations, light and X-rays. Light, with its longer wavelength (5000–6000 Å), can reveal only limited information about crystal structures, whereas X-rays with wavelengths of less than about 2 Å can be used to determine the relative positions of atoms in crystals. A preliminary examination of a crystal aims to determine its space group and unit-cell dimensions, and may be carried out by a combination of optical and X-ray techniques. The optical methods described here are simple, but, nevertheless, often very effective; they should be regarded as a desirable prerequisite to an X-ray structure determination.
