Experimental and computed IR absorption spectra of the S=O stretching mode at different concentrations in binary DMSO/water mixtures. Computed spectra were obtained using the map of Oh and Baiz. Vertical bars represent the average experimental frequencies of the four DMSO species present in solution: singly hydrogen-bonded (1HB), doubly-hydrogen bonded (2HB), Aggregate (Agg), and non-hydrogen bonded (Free) from low to high frequency respectively.
