Raman spectra of isolated single-walled carbon nanotubes (SWNTs) were obtained for a wide range of laser excitation energies to study the resonance excitation window of the radial breathing mode feature for members of (2n+m) families. A chiral angle (theta) dependence of the resonance window width (Gamma) was observed, which is much stronger than the diameter dependence. The implications of this work on nanotube metrology are discussed.
