Abstract
Using density functional theory results as input data into the tight binding method for induced representations (based on the line group symmetry concept) we calculate optical conductivity tensor for single wall carbon nanotubes. Optical transition matrix elements are calculated exactly, out of completely symmetry adapted Bloch eigenfunctions. The results obtained can improve optical spectroscopy method as single-wall carbon nanotubes macroscopic sample characterization tool.Keywords
