Infrared and Raman Spectra and Valence Force Constants of Iodine Oxide Pentafluoride (IOF5)

Abstract

The infrared and Raman spectra of IOF₅ have been recorded. The data have been tabulated, and assignments made on the basis of an octahedral structure with a fourfold symmetry axis. Valence force constants have been calculated. The bond angles are close to 90°, and there is an indication that the equatorial I–F bond lengths are about the same as the axial I–F bond length.
