%X Double-walled carbon nanotubes (DWCNT) are made of two concentric and weakly van der Waals coupled single-walled carbon nanotubes (SWCNT), also called layers. DWCNTs are the simplest systems for studying the mechanical and electronic interactions between concentric carbon layers. In this communication, we review recent results concerning the intrinsic features of phonons of DWCNTs obtained from Raman experiments performed on index-identified DWCNTs. The effect of the interlayer distance on the strength of the mechanical coupling between the layers, and thus on the frequencies of the Raman-active modes, namely the radial breathing-like modes (RBLM) [1] and G-modes [2], are evidenced and discussed.
