    • Fraction f36 has a peak at 1061 nm that was unassigned previously (marked by *). The lack of relative shifting between emission features causes us to reject the possibility that this feature is less shifted (10, 2). It is possible that this feature is the (11, 0) nanotube at a nominal v 1 (c 1) transition when unshifted to a lower energy of 1039 nm and a v2(c2) transition at 741 nm. The origin of this feature can be identified using fluorescence excitation profiles, and this work is currently underway.

    • note
    • We note that in normalizing these fractions to their solvent D-O Raman mode that f39 is considerably more concentrated than the starting material. This may be an artifact of the reconcentration process that attempted to equalize the total added volume but apparently created disparities in the concentrations of the SWNT material (see refs 6 and 7). Nontube impurities, particularly fullerene fragments, may elute from the column first and change the mass concentration of the early fractions. All of the above analysis in this work considers relative peak intensities or shifts and is therefore unaffected by this disparity with this one fraction.
