The intermolecular potential of Ar-HCCH is modelled using an atom-atom pairwise-additive approximation, including anisotropic Ar-C repulsions. Close-coupling calculations of the van der Waals bending, stretching and rotational states are carried out. Three potentials that reproduce the experimental
Ranm spectra of the lattice regions of poIyorystaliine hydrogen chloride, hydrogen bromide, deutcrium chloride and deuterium bromide at 79 and 18ยฐK ore reported. The Iattice modes are assigned in accordance with the known crystal structures, and their frequencies compared with those obtained from ca
