Résumé:
Polarized Raman spectroscopy is used to study orientational order and resonance in fibers of SWNT. The polarized Raman intensity follows essentially the same angle dependence for both radial breathing mode and tangential modes and for both semi-conducting and metallic nanotubes. A simple resonant model is proposed, which provides good fits of two sets of data for two different fibers. (C) 2002 Elsevier Science B.V. All rights reserved.
