✦ Synopsis

We present a comparative analysis of the vibrational and structural properties of carbon nanotubes. The first-order Raman spectrum exhibits two lines at 1582 cm -' and at 1350 cm-'. The observed ratio of the integrated intensity of these lines was found to be different as compared to polycrystalline graphite. The position and intensity of the line around 1350 cm-' strongly depend on the energy of the exciting laser line. This dispersion effect is again different from the dispersion in nanocrystalline graphite. It is discussed in terms of a photoselective resonance process. Transmission infrared spectra of the nanotubes show one broad and asymmetric line at 1575 cm-' and a weaker line at 868 cm-'.

Isotopically enriched single-wall carbon nanotubes with different 13 C concentrations were investigated by resonant Raman spectroscopy. Linear reductions of the Raman frequencies with an increase of 13 C concentration are observed for the different nanotube Raman modes, and the effect of the reduced

## Abstract This paper presents an overview on the principles of tip‐enhanced Raman spectroscopy (TERS). The technique can be used to record Raman images of carbon nanotubes with high spatial resolution. The high resolution is made possible by local enhancement of the incident and scattered fields.

We present resonant-Raman scattering results on single and multi-walled carbon nanotubes in the range 1.5 to 2.6 eV. In addition to the known resonance of metallic tubes with a maximum at % 1:9 eV we determine the resonance profile of semiconducting single-walled tubes. For a diameter of d 0 1.3 nm
