Notes:
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-d6)-DCl was also prepared and studied. Vibrational data suggest the presence of a (DMSOHOSMD)+ cation with strong (O—H—O)+ 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.
