Abstract
We performed spatially resolved measurements on multiwalled carbon nan otubes. The first-order spectra do not reveal any characteristic, fing erprint-like signal as it is known from singlewalled nanotubes. Instea d, we observed at special positions on the sample Raman-active vibrati onal modes in the low-energy region, which, as we show, differ from th ose of singlewalled nanotubes and graphite. Possible explanations for the origin of these modes will be given.
