Chemical graph theory

Chemical graph theory is a special part of science that connects math and chemistry. It uses ideas from graph theory—which studies connections and patterns—to help understand chemical processes. This field looks at molecules, the tiny building blocks of everything around us, and represents them as graphs to learn more about their properties.

Some important scientists helped start this field, including Alexandru Balaban, Ante Graovac, Iván Gutman, Haruo Hosoya, Milan Randić, Nenad Trinajstić, and Harry Wiener.

People who support chemical graph theory believe that looking at molecules as graphs gives useful information about how chemicals behave. Others think graphs are only a small part of chemical research. One interesting way this theory is used is to describe materials like crystals using special kinds of graphs.
