In this paper, we investigate how photoluminescence excitation spectra of single‐walled carbon nanotubes are influenced by experimental conditions. The use of incoherent light sources leads to a broadening of the second excitonic transition. We describe the broadening by a straight forward simulation and deliver the width of the second excitonic transition free of experimental influences. A set of simulated data allows for the correction of experimental influences for arbitrary nanotubes chiralities and excitation bandpasses.
