It is shown that it is possible to obtain the phonon frequency distribution function (FDF) of aligned multi-walled carbon nanotubes (MWNT) by unfolding its temperature variation of specific heat in the temperature range 1.8-250 K. An anisotropic dynamical model which takes into account the presence of two-dimensional modes on the surface of the tube and the intertube coupling has been used as a trial function to carry out the unfolding process numerically. The aligned MWNT sample turns out to be somewhat similar to graphite.
