A resonant Raman scattering study on single wall carbon nanotubes (SWCNTs) decorated with terpyridine–Ru(II)–terpyridine (tpy–Ru(II)–tpy) moieties is presented. We compare samples synthesized bearing either monomeric or polymeric side chain tpy–Ru(II)–tpy dicomplexes. From the resonance profiles of the radial breathing modes (RBMs) the chiral indices of the corresponding tubes are assigned. We observe significant changes in the transition energies and the widths of the resonance windows due to chemical modification of SWCNTs. SWCNT, decorated with tpy–Ru–tpy–G1 monomer, following the “grafting to” approach.
