Dimethylsulphoxide (DMSO)‐hydrogen chloride interactions have been studied by means of Raman and infrared spectroscopy both in solid 1:1 adducts and in liquid mixtures with DMSO:HCl molar ratios >2. The deuterated analogue solid 1:1 (DMSO‐ d 6 )‐DCl was also prepared and studied. Vibrational data suggest the presence of a (DMSOHOSMD) + cation with strong (OHO) + hydrogen bonds both in the solid adducts and in the liquid mixtures. In the solid adducts the (CIHCl) − anion may be present. A relation between some biological properties of DMSO and its protonation is suggested.
