✦ Synopsis

Laser Raman spectroscopy has been applied to the study of various carbons ranging from highly graphitized to amorphous materials. A calculation is presented for such materials based on the assumption of short correlation lengths for normal modes that break the wave-vector selection rules. This calculation leads to expressions for the first-order Raman scattering intensity in terms of the vibrational density of states of a single graphite layer weighted by the electron-phonon coupling of the modes to the electromagnetic radiation.

## Abstract Raman scattering from double‐walled carbon nanotubes is reported with particular emphasis on the response from the radial breathing mode (RBM) of the inner‐shell tubes. The unexpected large number of very narrow lines observed is explained by the growth of one and the same inner tube ty
