The first four flexural thermal vibrational modes of single walled carbon nanotubes
(SWCNTs) of various lengths and radii were studied using atomistic molecular dy-
namics within the framework of the Brenner interatomic potential and Fourier anal-
ysis. These simulations provide clear evidence for the failure of simplistic analytic
models to accurately extract resonance frequencies as the ratio, (R/L), between the
tube radius and the length increases. They are in excellent agreement with the Tim-
