Abstract

An analysis of the Raman spectra of single‐walled HiPco carbon nanotube powder using laser energies of 1.92 eV, 2.4 eV, 2.5 eV and 2.7 eV, including a comparison of the Stokes and anti‐Stokes contributions is presented. The diameter distribution was determined to be 0.8 – 1.2 nm from the spectral positioning of the Radial Breathing Modes. The diameter distribution is consistent with that determined by NIR absorption spectroscopy. At all excitation energies the profile of the G‐line (≈ 1580cm−1) indicates a predominance of semiconducting tubes although at 2.4 eV there is some indication of some contribution from metallic tubes. In all cases the anti Stokes line was weak and the Stokes/anti Stokes ratio was at least an order of magnitude indicating at most weak resonance enhancement in either.
