12. We applied Lorentzian shape analysis on peak B to yield information about the fractional abundance (subpeak area) of the SWNT diameter groups. The full width at the half maximum of all subpeaks was chosen constant on the diameter scale (0.13 nm). Due to the origin of the absorption peaks as a result of DOS singularities, an asymmetric pulse-like shape of the subpeaks has to be expected. Therefore, our fitting procedure should result in a slight overestimation of the abundance of SWNT with small diameters. The usage of the weaker peak B instead of peak A is a compromise between subpeak discrimination ability, subpeak area and fractional abundance determination accuracy.
