This book gives an insight to the applications of graph theory in various fields including chemistry. The most significant tool of chemical graph theory is topological index that is used to gather data about a chemical compound and subsequent studies of quantitative structure-activity relationships/quantitative structure-property relationships (QSAR/QSPRs) analysis. The data obtained by topological indices are extensively used by chemists in drug design. It highlights about the various tools like graph operator, transformations and bounds related to chemical graph theory.

This book aims at providing the concepts of topological indices and its applications in various fields. Topological indices capture the symmetry of molecular structure and provide a mathematical language to predict physical and chemical properties of chemical compounds. In the fields of chemical graph theory, molecular topology, and mathematical chemistry a topological index also known as a connectivity index. These topological indices are numerical parameters of a graph which characterize its topology and are usually graph invariant. Also, this book offers examples of topological indices in...
