We present resonant-Raman scattering results on single and multi-walled carbon nanotubes in the range 1.5 to 2.6 eV. In addition to the known resonance of metallic tubes with a maximum at % 1:9 eV we determine the resonance profile of semiconducting single-walled tubes. For a diameter of d 0 1.3 nm
Antisymmetric resonant vibrational Baman scattering is studied using time-reversal symmetry. Under the Born-Oppenheimer approximation, for even-electron systems with the ground and the excited vibronic states belonging to real representations, the antisymmetric resonant Baman transition polarizabili
