Abstract

Above To = 196 K, white phosphorus, a solid composed of P4 molecules, exhibits a plastic crystal phase. Below this temperature, the structure is triclinic and orientationally ordered, with six molecules in a unit cell. Using inelastic neutron scattering on a polycrystalline sample, observations were made of the rapid reorientational motions above To, and the librational modes below To. In addition, neutron powder diffraction was used to investigate the crystal structures above and below To
