spaceGroupMultiplicity

<h:div class="summary">SpaceGroup multiplicity.</h:div>
<h:div class="description">Normally for an atom. This attribute gives the spaceGroup multiplicity of the molecule and is independent of any atomic information. No default, and it may take any positive integer value (though values are normally between 1 and 192. It represents the number of symmetry operations (without cell translations) that transform the atom into itself. Thus an atom on a centre of symmetry can have a spaceGroupMultiplicity of 2. The spaceGroupMultiplicity can be deduced from a knowledge of the coordinates and the spaceGroup operators and so is formally redundant but this is a useful convenience operator. Some crystallographic experiments report this attribute as, for example, the IUCr CIF item 'atom_site_symmetry_multiplicity'. Distinguish carefully from occupancy which represents incomplete occupation of a site.</h:div>
