Types of twins –<br />
Non-merohedral twin<br />
• Twin opera<strong>to</strong>r is arbitrary but often<br />
a rotation of 180°<br />
• no exact overlap of reciprocal<br />
lattice points<br />
• Close, split and overlapping<br />
reflections<br />
• Special <strong>to</strong>ols for cell determination<br />
• Data integration requires more<br />
than one orientation matrix<br />
• Structure solution not difficult after<br />
