TL;DR: In this paper, a non-orthogonal density-functional based tight-binding calculation for the electronic transition energies in single-wall carbon nanotubes is presented. But the method does not consider the curvature-induced rehybridization of the electronic orbitals, long-range atomic interactions, and geometrical structure relaxation all have a significant impact on the transition energy in the small diameter limit, and the results show good agreement with the experimental transition energies observed by photoluminescence and resonance Raman spectroscopy.
