| Abstract: | The molecular structure of gaseous OVF3 has been determined by electron diffraction to be: rg(V-O) = 1.570(5) Å, rg(V-F) = 1.729(2) Å and ∠α(OVF) = 107.5(4)°. A modified force field has been fitted to results from spectroscopic as well as diffractional studies. A similar attempt to determine the force field for OVCl3 was not as successful as for OVF3, probably because the Coriolis constants are less accurately determined for that molecule. |
