Hosoya and Harary Polynomials of T O X ( n ) , R T O X ( n ) , T S L ( n ) and R T S L ( n )

In the fields of chemical graph theory, topological index is a type of a molecular descriptor that is calculated based on the graph of a chemical compound. In 1947, Wiener introduced “path number” which is now known as Wiener index and is the oldest topological index related to molecular branching. Hosoya polynomial plays a vital role in determining Wiener index. In this report, we computed the Hosoya and the Harary polynomials for T O X ( n ) , R T O X ( n ) , T S L ( n ) , and R T S L ( n ) networks. Moreover, we computed serval distance based topological indices, for example, Wiener index, Harary index, and multiplicative version of wiener index.
