13 C nuclear magnetic resonance on functionalized single wall carbon nanoutubes is reported. We present a possible chemical modification of the nanotube in order to get soluble materials. NMR is used in order to study in details the chemical changes and their reversiblities. In particular, acid groups, inequivalent sp 2 and sp 3 carbons attributed to functionalized nanotubes are identified and characterized.
