Title: FORCE CONSTANT FOR HEXAFLUORIDES XF$sub 6$ (in Italian)

Abstract

Recent spectroscopic studies showed that XF/sub 6/ hexafluorides (where x = S, Se, Te, Mo, W, U, Re, Ir, Np, or Pu) are in a group with ON symmetry and have a regular octahedron structure. Previous attempts to calculate the force constants using the simple valency force field or the orbital valency force field have been in error. A new series of calculations for the ten compounds listed above is offered which uses two types of potentials: A quadratic potential made up of four interaction constants and a potential of the Bradley-Urey type. The force constants calculated in the first case exactly represent the experimental frequency, the calculations in the second case represent the experimental frequency with good approximation for only five of the molecules.
