Urey-Bradley potential constants for second-row fluorides

Abstract

To provide an internally consistent set of force constants for the fluorides of second-row elements, a normal coordinate analysis, based on the Urey-Bradley potential function, has been performed for SiF₂, SiF₄, PF₃, PF₅, SF₄, SF₆ ClF, ClF₃, and ClF₅. Some limitations of this potential function, imposed by molecular symmetry, are indicated. aluminium removal from the clay surface.
