Using
ab initio and
parametrized techniques, we determine the equilibrium structure of an
ordered "bundle" of (10,10) carbon nanotubes. Due to the small inter-tube
interaction and lattice frustration, we predict a very soft libration mode
to occur at <>n ª 12
cm-1. This mode is predicted to disappear above the
orientational melting temperature which marks the onset of free tube
rotations about their axis. We discuss the effect of the weak inter-tube
coupling and orientational disorder on the electronic structure near
the Fermi level.
