    • The enhanced intensity for the RBM modes is seen for all B-SWNT samples, in both dry and solvated forms. This implies that the enhanced intensity is intrinsic to the B-SWNTs themselves and does not result from SWNT-surfactant interactions. Our assertion that the enhancement is due to an increase in the absorbance cross section is supported by differences in the absorbance spectra for B-SWNTs and C-SWNTs when the spectra are normalized to the rising background that peaks in the ultraviolet. When normalized in this manner, the integrated area underneath each grouping of van Hove singularities is always significantly greater for the B-SWNTs than for the C-SWNTs. We are in the process of carefully quantifying the absorbance cross sections for each type of SWNT and plan to report on this effect in the near future
