Determination of the Bravais class for a number of incommensurate crystals

Abstract

For a number of incommensurate crystal phases with a one-dimensional modulation and for all those with a higher-dimensional modulation which are known to the authors, the Bravais class is determined. This is done partly to illustrate the use of the complete list of Bravais classes published in a previous paper [Janner, Janssen & de Wolff (1983). Acta Cryst. A39, 658-666] partly to give an overview of the crystals having higher-dimensional modulation.
