5.3.2.3.3. Combined methods

| top | pdf |

The most effective photographic method of lattice-parameter measurement is a combination of two techniques (Buerger, 1942[link]; Luger, 1980[link]), which makes it possible to obtain a three-dimensional picture of the reciprocal lattice; for example: the rotation method with the Weissenberg (lower accuracy); or the precession (or the Weissenberg) method with the de Jong–Bouman (higher accuracy).

A suitable combination of the two methods will determine all the lattice parameters, even for monoclinic and triclinic systems, from one crystal mounting. This problem has been discussed and resolved by Buerger (1942[link], pp. 388–390), Hulme (1966[link]), and Hebert (1978[link]). Wölfel (1971[link]) has constructed a special instrument for this task, being a combination of a de Jong–Bouman and a precession camera.
