Normal coordinate analysis of Re(VII)O 4- , Re(VII)O 3 Cl and Re(VII)O 3 Br

Abstract

Using published infra-red and Raman data, the potential constants of ReO₄ ^-, ReO₃Cl and ReO₃Br have been determined in a modified Urey-Bradley field. A normal coordinate analysis have been carried within the formalism of Wilson's F-G matrix method, and the force constants have been evaluated by a computer routine which refined the differences of experimental and calculated frequencies in the least-square sense. Transferability of Urey-Bradley force constants has been assumed.
