We present a theoretical model to describe the double-resonant scattering process in arbitrary carbon nanotubes. We use this approach to investigate the defect-induced \(D\) mode in CNTs and unravel the dependence of the \(D\)-mode frequency on the CNT diameter and on the energy of the resonant opti...
