Abstract Here, a theory of optical scattering by single‐wall carbon nanotube using modal expansion of the scattered and transmitted fields is developed. The effective‐boundary condition, derived previously using accurate quantum‐mechanical one‐electron tight‐biding approach, is employed to obtain the unknown coefficients in the series expansion. The complete scattered field is then derived analytically and compared to Rayleigh spectroscopy experiments. Very good agreement with the empirical data is observed. The theory is shown to produce expressions for the dielectric function of carbon nanotubes that can be used for further study of the optical and electronic structure. © 2007 Wiley Periodicals, Inc.
