Abstract
We use the spectral moments method in the framework of the bond-polarization theory to calculate polarized nonresonant Raman spectra of chiral and achiral single-wall carbon nanotubes as a function of their diameter and length. In a previous approach, an investigation of finite-size effects was limited to a narrow length range (below 50 Å). The present work extends the analysis to a larger range of finite lengths (from 20 to 850 Å) as well as to achiral and chiral tubes of different diameters.Keywords
