Query: Multi-spectroscopic investigation of the structure of single-wall carbon
  nanotubes   We present a multispectroscopic structural study of various nanotube samples
with different tube diameters. We determine for each sample the mean bundle and
tube diameter as well as the tube diameter distribution. The possibility to
work on SWNT of various structural characteristics opens new opportunities to
correlate the nanotube structure and their physical properties.
