Raman spectra of C60 single crystals, in the pentagon pinch mode frequency region, have been measured as a function of hydrostatic pressure up to 7.2 GPa at room temperature. The softening of the Ag(2) and Hg(8) modes in the pressure region up to 0.4 GPa indicate the orientational ordering phase tra
Changes in the vibrational response of single-walled carbon nanotubes (SWCNTs) resulting from the introduction of structural defects on their body were studied using resonance Raman spectroscopy. Structural defects were introduced on the SWCNTs by subjecting them to carboxylation for different inter
