Temporal fluctuations of surface-enhanced Raman scattering spectra of purified and oxidised single walled carbon nanotubes have been observed. SERRS spectra were recorded that possessed fluctuating spectral profiles, these profiles possessed randomly fluctuation peak intensities and positions. Observation of bands in the 1000 to 1200 cm-1 frequency window was observed. A series of peaks in this window were observed to coincide with peak positions that have been assigned to arise from Stone-Thrower-Wales and heptagonal-pentagonal intramolecular junction defects on the nanotubes surface. We find that these peaks also occur for chemically treated SWCNTS.
