The electronic spectra of carbon nanotubes and other nanoscale systems are quantized because of their small radii. Similar quantization in the phonon spectra has been difficult to observe because of the far smaller energy scale. We probed this regime by measuring the temperature-dependent specific heat of purified single-wall nanotubes. Thee data show direct evidence of one-dimensional quanitized phonon subbands. Above 4 K, they are in excellent agreement with model calculations of individual nanotubes and differ markedly from the specific heat of two-dimensional graphene or three-dimensional graphite. Detailed modeling yields an energy of 4.3 meV for the lowest quantized phonon subband and a tube-tube (or "lattice") Debye energy of 1.1 meV, implying a small intertube coupling in bundles.
