Abstract

The Y-index and coindex are degree based molecular structure descriptors that have been shown to give a high degree of predictability compare to Zagreb indices and F-index and their coindices for some physicochemical properties of octane isomers. In this paper, we studied the Y — index and Y — coindex for certain important chemical structures like line graphs of the V C5C7[p; q] and HC5C7[p; q] nanotubes and their molecular complement graph. Moreover, we defined Y — polynomial of graph G and applied it on the line graphs of the V C5C7[p; q] and HC5C7[p; q] nanotubes. These ex-plicit formulae can correlate the chemical structure of molecular graph of nanotube to information about their physical structure.
