[email protected] Abstract:In this paper, we propose the product connectivity Gourava index of a molecular graph. In the chemical graph theory, the connectivity indices are applied to measure the chemical characteristics of compounds. In this paper, we compute the product connectivity Gourava index for certain important chemical structures like tetracenic nanotubes and tetracenic nanotori. Also the product connectivity Gourava index of some standard classes of graphs are determined. Keywords: product connectivity Gourava index, nanostructures. Mathematicas Subject Classification: 05C05, 05C12, 05C35.
