MOLECULAR-STRUCTURE OF VINYLFLUORIDE IN THE GAS-PHASE AS DETERMINED FROM ELECTRON-DIFFRACTION AND MICROWAVE DATA

The structure of vinylfluoride (fluoroethene) has been determined from gas-phase electron diffraction data, rotational constants of the parent species, the B and C rotational constants of five deuterated species and calculated vibrational amplitudes. From a joint analysis of these data, all weighted in accordance with their relative estimated uncertainties, the following rg bond distances and rav bond angles were derived: CC = 1.330 ± 0.018 Å, CF = 1.351 ± 0.015 Å, average CH = 1.105 ± 0.015 Å, ∠ CCF = 121.5 ± 0.2°, ∠ C(2)C(1)H = 131 ± 3°, average ∠ C(1)C(2)H = 120 ± 2°. The uncertainties represent the estimated limits of total error. © 1979.
