KNOTS AND GRAPHS IN CHEMISTRY

This paper presents a knot theoretic approach to the study of molecula r graphs. It provides examples of molecular knots and links as well as other topologically complex molecules. The paper discusses various to pological problems and theorems which were motivated by questions in c hemistry. Some of these results have direct applications to the analys is of molecular structures, while other results, though arising out of questions about chemistry, are purely topological in nature.
