The present thesis constitutes a set of experimental studies on the effect of high pressures on single wall carbon nanotubes, individualized, closed or open, therefore empty or filled with water. High-pressure techniques and Raman spectroscopy were combined to study the radial collapse, as well to probe the pressure-induced modifications. Chirality-resolved pressure derivatives were obtained for the radial breathing modes (RBM). The RBM of water-filled could be observed at pressures higher than those of empty. After a high-pressure cycle, empty nanotubes of larger diameters were not detectable anymore, while sub nanometric diameter ones became filled with water. Such observations suggest that thinner nanotubes have better pressure-stability...
