Polarized Raman spectra were obtained from a rope of aligned semiconducting single-wall nanotubes (SWNTs) in the vicinity of the D band and the G band. Based on group theory analysis and related theoretical predictions, the G-band profile was deconvolved into four intrinsic SWNT components with the following symmetry assignments: 1549cm−1 [E2(E2g)], 1567cm−1 [A(A1g) + E1(E1g)], 1590cm−1 [A(A1g) + E1(E1g)] and 1607cm−1[E2(E2g)]. The frequency shifts of the tangential G modes from the 2D graphitelike E2g2 frequency are discussed in terms of the nanotube geometry.
