Bottom: representative Raman spectrum in the low-frequency RBM range from a typical non-optimized growth experiment in ARES (laser excitation at 532 nm). Top: Kataura plot showing the possible matches for SWCNTs (solid red data points) within the chosen frequency ranges (shaded areas). There are three matches for the RBM at 225 cm−1 and two for the 265 cm−1 peak. The dashed horizontal lines in the Kataura plot represent the resonance window (± 0.1 eV) for the SWCNTs.
