a
Peak positions and spectral widths for the inner and outer walls of the C8S3 nanotubes are obtained from single-nanotube spectroscopy in comparison to that of the nanotube ensemble spectrum. ⟨···⟩ denotes the average over individual nanotube spectra with the error margins referring to the standard error of the mean. The width of the respective parameter distribution is specified as its standard deviation (SD).
