Abstract

This chapter provides a general overview of the process of identifying cell parameters from a powder diffraction pattern. The main theoretical, computational and applicative approaches are described. In particular, the chapter deals with the basic concepts of a crystalline lattice, indexing equations, figures of merit, and traditional and non-traditional methods for solving the indexation problem. The most widely used indexing programs are discussed and examples of their applications are given.
