The Raman spectrum of liquid trifluoromethylthiosulphenyl chloride and its IR spectra in the vapour and solid phases in neon and argon matrices were recorded. Polarized Raman spectra of liquid trifluoromethylthiosulphenyl chloride suggest C 1 symmetry. Assignment of 14 of the 15 fundamental vibrations is carried out. A correlation between the S‐‐S stretching wavenumber and the sum of the group electronegativities of the disulphan substituents is proposed. The valence force constants were calculated by semi‐empirical methods and the values obtained compare favourably with results from previous calculations on related compounds.
