Potential constants of some inorganic hexahalides

Abstract

Using recently published Infrared and Raman data, the Urey‐Bradley constants of ReCl²⁻₆, ReBr²⁻₆ and OsCl²⁻₆ have been determined. The treatment has been carried within the formalism of WILSON'S F‐G matrix method, and the force constants have been calculated by a computer routine which refined approximate values in the least square sense.
