The <i>crystal</i> program is dedicated to perform the <a href="/wiki/Self_consistent_field" class="mw-redirect" title="Self consistent field">SCF</a> calculations, the geometry optimizations, and the frequency calculations for the structures given in input. At the end of the SCF process, the program crystal writes information on the crystalline system and its wave function as unformatted sequential data in <a href="/wiki/Fortran" title="Fortran">Fortran</a> unit 9, and as formatted data in Fortran unit 98. One-electron properties and wave function analysis can be computed from the SCF wave function by running the program <i>properties</i>. </p><p>The main advantage of the crystal code is due to the deep and optimized exploitation of symmetry, at all levels of calculation (SCF as well gradients and vibrational frequencies calculations). This allows significant reduction of the computational cost for periodic calculations. Note that while the symmetry generally reduces to identity in large molecules, large crystalline system usually show many symmetry operators. </p> <div class="mw-heading mw-heading2"><h2 id="See_also">See also</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=CRYSTAL_(software)&action=edit&section=2" title="Edit section: See also"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <ul><li><a href="/wiki/Crystal_structure" title="Crystal structure">Crystal structure</a></li> <li><a href="/wiki/Mercury_(crystallography)" title="Mercury (crystallography)">Mercury</a></li> <li><a href="/wiki/List_of_quantum_chemistry_and_solid_state_physics_software" class="mw-redirect" title="List of quantum chemistry and solid state physics software">Quantum chemistry programs</a></li></ul> <div class="mw-heading mw-heading2"><h2 id="References">References</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=CRYSTAL_(software)&action=edit&section=3" title="Edit section: References"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <div class="mw-references-wrap"><ol class="references"> <li id="cite_note-1"><span class="mw-cite-backlink"><b><a href="#cite_ref-1">^</a></b></span> <span class="reference-text"><i>Computational Chemistry</i>, David Young, Wiley-Interscience, 2001.
