Abstract

By a simple dynamical model it is shown that the radial breathing mode of single wall carbon nanotubes is not exactly radial: its longitudinal and circumferential components are non-vanishing and both diameter and chirality dependent. However, the radial component is only diameter sensitive; likewise the frequency.
