<p>during a polymorphic transition delineates polymorphism. For example, <a href="page.php?w=isomerization">isomerization</a> can often lead to polymorphic transitions. However, <a href="page.php?w=Tautomer">tautomerism</a> (dynamic isomerization) leads to chemical change, not polymorphism. As well, <a href="page.php?w=allotropy">allotropy</a> of elements and polymorphism have been linked historically. However, allotropes of an element are not always polymorphs. A common example is the <a href="page.php?w=allotropes_of_carbon">allotropes of carbon</a>,</p><p>
