<h:div class="description" xmlns:h="http://www.w3.org/1999/xhtml">
<h:p>The atoms need not be formally bonded. It can be used for:</h:p>
<h:ul>
<h:li>Recording experimentally determined torsion angles (e.g. in
a crystallographic paper).</h:li>
<h:li>Providing the torsion component for internal coordinates (e.g.
z-matrix).</h:li>
</h:ul>
<h:p>Note that the order of atoms is important.</h:p>
