A chiral angle (θ) dependence of the resonance window width () was observed, which is much stronger than the diameter dependence. The implications of this work on nanotube metrology are discussed. © 2010 American Institute of Physics.Chiral angles; Radial breathing mode; Raman spectra; Resonance excitation; Resonance window; Carbon nanotubes; Laser excitation; Raman spectroscopy; Resonance; Single-walled carbon nanotubes (SWCN)Chiral angle dependence of resonance window widths in (2n+m) families of single-walled carbon nanotubesjournal article10.1063/1.33594272-s2.0-77949730395WOS:000275588000085
