A Study of Indium phosphide and line graph of subdivision graph of H-naphtalenic nano-sheet via irregularity indices

In this article, we have taken the molecular graph of indium phosphide InP[m, n] and line graph of subdivision graph of H-naphtalenicnano-sheet L(S(H(r, s))). Irregularity indices play an important role to describe the quantitative characterization of the non-regular graphs. In various problems and applications, particularly in subject of chemistry and material engineering irregular indices have so many uses, thus it is very important to know about the irregularity of a molecular structure. Moreover, the evaluation of the irregularity of graphs is an important not only for QSPR and QSAR but also very effective for the measuring the entropy, melting and boiling points, enthalpy of vaporization and toxicity. We have also discussed the graphical behaviors of the above indicated structures.
