Article abstract of DOI:10.1007/BF00750880

The structure of the TiF4 molecule has been studied by gaseous electron diffraction at a temperature of 689 +/- 20 deg K.Simultaneous treatment of the data, obtained at two temperatures (689 and 475 deg K) , in the harmonic approximation gave the value of the equilibirum internuclear distance r_e^h(Ti-F) = 1.745(3) Angstroem, the complete force field, and the frequencies of the vibrations: ν₁ = 695(20), ν₂ = 179(8), ν₃ = 787(5), n₄ = 225(20) cm^-1.The force constants obtained are equal to the values obtained by the simultaneous treatment of the spectral and electron diffraction data.
