The D band to G band intensity ratio in the Raman spectroscopy has been widely used to identify the degree of covalent functionalizations of single-walled carbon nanotubes (SWCNTs). The Raman D band at ∼1350 cm−1 is extremely sensitive to the sidewall sp3 scattering centers created by covalent funct...
