We show that the radial breathing modes are upshifted in suspensions due to the molecular pressure of the solvent. On the other hand, we directly probe charge transfer in solutions of nanotube polyelectrolytes and its reversibility after oxydation in air. %G English %2 https://hal.science/hal-00005795/document %2 https://hal.science/hal-00005795/file/Raman.pdf %L hal-00005795 %U https://hal.science/hal-00005795 %~ CNRS %~ UNIV-MONTP2 %~ LCVN %~ CRPP %~ UNIV-MONTPELLIER %~ UM1-UM2 %~ TEST2-HALCNRS
