We present resonant Raman measurements on carbon nanotubes functionalized with primary alkyl groups of different chain length. From the resonance profiles of the radial breathing mode (RBM) we assign the chiral indices of the tubes in order to study the selective reactivity of different tubes. We focus on diameter dependence showing inversely proportional behaviour to diameter for both metallic and semiconducting nanotubes. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
