The Molecular Structure of Formyl Fluoride

The structure of HCOF has been investigated by electron diffraction in the gas phase. The parameters were refined by a least squares technique based upon the observations and calculated intensity curves. The parameter values and limits of error (taken as σ) are C-F = 1.351 ± 0.013 Å., C=O = 1.192 ± 0.011 A7., O•••F = 2.225 ± 0.019 Å., C-F/C=O = 1.134 ± 0.005 and ∠O-C-F = 121.9 ± 0.9°.
