Abstract: In the study of QSPR/QSAR, we used topological indices to predict or estimate the bioactivity of chemical compounds. The harmonic index is an useful tool in predicting the heats of vaporizations, critical temperatures and melting points. In this paper, we compute the harmonic index of certain carbon nanotubes $TUC_4C_8[m,n]$ and $TUC_4[m,n]$, respectively.

Keywords: Carbon nanotubes, harmonic polynomial, harmonic index.
