Abstract
Polarized Raman spectra were obtained from a rope of aligned semiconducting single-wall nanotubes (SWNTs) in the vicinity of the band and the band. Based on group theory analysis and related theoretical predictions, the -band profile was deconvolved into four intrinsic SWNT components with the following symmetry assignments: , , and . The frequency shifts of the tangential modes from the graphitelike frequency are discussed in terms of the nanotube geometry.
