Further Spectroscopic Properties of Carbon Nanotubes

Besides those spectroscopic properties presented so far, there is a variety of further phenomena that have been studied on carbon nanotubes, either in experiment or 

By now, it has been possible to overcome at least some of these problems and to obtain spectra of carbon nanotubes both in solution and in solid state. Especially the removal of catalyst residues by magnetic separation led to a clear improvement of spectrum quality.
