Abstract

A vibrational analysis of the electron diffraction intensity data of iron trifluoride provides firm evidence for the planarity of this molecule. The optimized deformation frequencies of iron trifluoride, ν2 110(17) and ν4 158(17) cm-1, appear to be much lower than the available estimates. The optimized symmetric streching frequency for aluminium trifluoride is 683(54) cm-1 from the joint analysis of electron diffraction intensities and vibrational frequencies. Force constants are also obtained for both molecules.
