In this work, we compare the pressure response of single- (SWCNTs), double- (DWCNTs) and multi-wall carbon nanotubes (MWCNTs), as reflected in the normalized pressure derivatives (Γ-parameters) of their radial breathing modes (RBMs), probed by Raman spectroscopy. The qualitative characteristics of the experimentally obtained Γvalues are well reproduced by a simple anharmonic model. In a nanotube system, the diameters and the number of the constituent coaxial tubes as well as their mutual interaction - strongly depending on their spacing - define its pressure response.
