Symmetry
Previous  Top  Next

Dialog Box - called from: Input1 Menu

The authority and source of information for crystal symmetry is normally the International Tables for X-ray Crystallography. However, any point- or space-group symmetry may be used for the atoms. There are several options for selecting or entering symmetry information.

Space group from table - Choose a space group by symbol or number.

Point group from table - Choose a crystallographic point group.

Cartesian matrices - Use non-standard or non-crystallographic point symmetry.

Custom point or space group - Enter all the individual operators.

Use no symmetry - Use no symmetry at all. Check Crystal to enable lattice translations - the space group will be P1.

Except for the last option, Use no symmetry, each choice calls up a sub-dialog.
