Resumen:
The Raman spectrum of liquid N-(trifluoromethyl)iminosulphur dichloride, CF3NSCl2 and the infrared spectrum
of its vapour phase were recorded. The observed features were consistent with the existence of only one conformer
with Cs symmetry, as derived by the reported electron-diffraction analysis. Theoretical vibrational spectra were also
determined using ab initio and Density Functional Theory (DFT) calculations at different levels of approximation.
For all except one of the torsional modes, experimental wavenumbers were obtained. A subsequent normal coordinate
analysis was performed using a torsional wavenumber calculated by theoretical methods.N-(trifluoromethyl)iminosulphur dichloride, CF3NSCl2 and the infrared spectrum
