Abstract
We choose naphthalene as a model system and perform a quasi-harmonic l attice dynamics calculation. The entropic and zero-point effects due t o the lattice phonons are investigated and some commonly used potentia l models are tested. We find that quite reliable predictions of the cr ystallographic structure and the phonon frequencies as a function of b oth temperature and pressure are feasible.
