Abstract Knowledge of electron–phonon coupling is essential for the understanding of many properties of carbon nanotubes. We present a comparative study of the coupling of electrons to totally symmetric phonons: the radial‐breathing mode and the high‐energy mode. The coupling of the high‐energy mode is stronger than of the radial‐breathing mode by a factor of ≈6. In both cases the matrix elements depend on chirality, diameter, family, and transition energy.
