Abstract
We studied the Raman intensities of the radial breathing mode(RBM) in carbon nanotubes excited resonantly into the first and second optical transitions of semiconducting nanotubes and the first transition of metallic nanotubes. Several variations in the maximum Raman intensities of different (n1, n2) nanotubes are observed from which we discuss the dependence on the nanotube family ν, the chiral angle θ and the optical transition Eii. By comparison to theory we attribute variations with ν and θ to variations in the exciton-phonon coupling. Differences between different Eii are dominated by variations in the linewidth of the optical transitions.
