The Conventional Bravais Unit Cell from Diffractometer Data

Abstract
With the use of modern single-crystal diffractometers for
structure determination, the preliminary photographic study of the
diffraction pattern is much abbreviated or even eliminated entirely.
The dangers inherent in this omission can be reduced by systematic
checking of the automatic features of diffractometer operation, and
this requires a full understanding of the methods. This paper (a)
describes how possible unit cell axes are found from 15-25
accurately centered reflections, in more detail than is easily
available elsewhere; (b) provides a step-by-step procedure for deriving
the reduced cell; and (c) indicates how International Tables
for X-Ray Crystallography can be used to deduce the conventional
Bravais cell from the reduced cell.
