maximum (FWHM) for the Lorentzian bands) of the fitted band components of the
G-band of SWCNTs, MWCNTs, and graphite, recorded at 532 nm excitation
wavelength, are presented in Table 4.1. As mentioned above, the other two components of the G-bands of the SWCNTs (CarboLex) and SWCNTs (Aldrich) were
fitted assuming a Lorentzian function, and the fitted peaks appeared at 1590 and
1606/1607 cm
−1 , respectively. The band at 1590 cm
−1 belongs to the A(A 1g ) and
