Lattice+dynamical calculations for evidently non-rigid molecules of aromatic hydrocarbons have been carried out on tetracene and pentacene. In these substances, "out-of-pf;ute" vibrations niix extensively with lattice vt%rations, and signif& cant differences can be noted between results from a Xgid-
