Baman scattering intensity of single-wall carbon nanotubes
非共振条件下单壁碳纳米管拉曼散射强度的计算

A study based on non-resonant bond polrizability model is maded on the Raman scattering intensity of single-wall carbon nanotube.The structure of nanotube,polarization of light and sample orientation dependence of the Raman intensity was discussed by varying the direction of the nanotube axis.It is found that the polarization of light have large effect on the Raman spectra,while the chirality of the carbon nanotube has little effect.The chirality and diameter dependence of the Raman intensity were calculated using the theory of randomly oriented particles.
