Champ de forces de symetrie locale de molecules cycliques: Partie I. L'hexachlorocyclotriphosphazène (NPCl 2) 3

Abstract

Normal coordinate analysis of hexachloroeyclotriphosphazene (NPCl 2) 3 using a local symmetry force field gives good agreement between the calculated and observed frequencies and permits assignments for the 30 normal vibrational modes to be proposed. The redundancy relations lead to the definition of 12 coordinates which are characteristic of the ring. These may be transferred to more complex molecules where this ring is present.
