| Abstract
| - Raman spectroscopy on surfactant-dispersed, aqueous suspensions of single-walled carbonnanotubes is used to verify the energies of interband transitions and validate the spectral assignments ofsemiconducting and metallic nanotubes determined by spectrofluorimetry for the former and Ramanexcitation profiles for the latter. The results are compiled into an experimentally based mapping of transitionversus nanotube diameter to revise those previously employed using single-electron theoretical treatments.Because this mapping provides the transitions associated with a precise chiral wrapping of a particularnanotube, it allows the monitoring of reaction pathways that are selective to the nanotube chirality vector.This is demonstrated using a model electron-transfer reaction of 4-chlorobenzenediazonium shown to beselective for metallic over semiconducting carbon nanotubes via charge-transfer stabilization of complexesat the surfaces of the former.
