Figure S2 Raman spectrum of Re2(CO)10@SWNT + I2 measured using a 532 nm excitation source. The spectrum is focussed on the low-frequency region and highlights the presence of two peaks at 106 and 175 cm-1 which are attributed to I3- and I5- respectively. However, the I5- band does have strong overlap with the radial breathing mode of the SWNTs.
