Abstract
AbstractResonant Raman scattering is a well‐known method for investigating the optical transitions in solids [1]. Here we show that the fully symmetric radial breathing mode (RBM) of carbon nanotubes can be used to derive an assignment of their chiral indices. Our assignment is based on a plot of the resonance maxima for the radial breathing modes as a function of laser excitation energy versus inverse ωRBM, a so‐called Kataura plot. Different from recent luminescence measurements [2], the chirality of both semiconducting and metallic nanotubes can be investigated. (© 2005 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
