We carried out Raman characterization of a highly folded individual serpentine (7,5) single-walled carbon nanotube (SWNT). Twenty five Raman peaks were observed, which included a radial breathing mode (RBMband), an overtone of RBM(2RBMband), an immediate-frequency band (IMF band), a disorder-induced band (Dband), a tangential band (Gband), an M band (1700-1900 cm-1), a combination mode of G and RBM (G+RBMband), a combination mode of in-plane transverse optic (iTO) phonon and longitudinal acoustic (LA) phonon (iTOLA band), an overtone of the D band (G'or 2D band), an overtone of the G band (2G band) and some other bands with unknown assignments. Further Raman measurements at different laser excitation wavelengths and different excitation polarization show that these Raman peaks are highly dependent on the excitation energy and the excitation polarization.
