Over the past few years, numerous re- searchers have been able to pursue a variety of novel avenues. A chemical graph is a named graph where the edges reflect chemical bonds between atoms and the vertices reflect the atoms of a compound. The investigation of topological indices is crucial for determining numerous physical and chemical characteristics of the under-investigation molecular struc- tures. Firstly, we focused on degree-based topological indices, namely the Randic index, atom bond connectivity index, geometric arithmetic index, the first and the second Zagreb indices and co-indices, the first and the second multiple Zagreb indices and co-indices, hyper Zagreb index, forgotten index, augmented Zagreb index, Balaban index, redefined Zagreb type indices, of Molecular Graph of Bismuth(|||) Iodide.en-USCIIT/FA20-BSM-020/LHRCIIT/FA20-BSM-072/LHRDr. Muhammad Kamran SiddiquiTopological IndicesThesis
