Describes CIF, the data exchange standard of crystallography. Provides: information for scientists who wish to record or use the results of a single-crystal or powder diffraction experiment; the data ontology necessary for designing interoperable computer applications; accompanying software including machine-readable CIF dictionaries, libraries and utility programs.
An essential guide and reference to CIF for programmers, data managers handling crystal-structure information and practising crystallographers.
A description of the relative alignment of the crystal cell axes to the Cartesian orthogonal axes as applied in the transformation matrix _atom_sites.Cartn_transf_matrix.Example:
|'a parallel to x; b in the plane of y and z'|
