The goal of our “complete experimental” approach was to relate the Raman response of an individual single‐walled carbon nanotubes (SWNT) to its ( n , m ) structure determined from an independent way. In this aim, a procedure including transmission electronic microscopy (TEM), Raman spectroscopy, and electron diffraction experiments on the same SWNT has been developed. The independent determinations of both structure and Raman features of semiconducting and metallic nanotubes allows to discuss several questions concerning: (i) the relation between diameter of the tubes and the radial breathing mode (RBM) frequency, (ii) the values and the nature of the $ E ^{\rm S}_{33} $ and $ E ^{\rm S}_{44} $ optical transition energies.
