Chlorocarbony fluorocarbonyl disulphide, CIC(O)SSC(O)F, was prepared from bis(fluorocarbonyl) disulphide and BCI 3 . IR data of the vapour, liquid and matrix‐isolated CIC(O)SSC(O)F at low temperature together with the Raman spectrum of the liquid suggest the existence of a more abundant non‐planar conformer with symmetry C 1 in both the vapour and liquid phases. For all but the torsional modes of this conformer wavenumbers are reported. However, the valence force constants were calculated by a semi‐empirical method. The study was complemented with the characterization of the compound by 19 F NMR and mass spectra.
