The IR ATR spectra of concentrated aqueous solutions containing from 90.68 to 99.98% H2SO4, (30°C) have been decomposed into individual bands by the method of differential moments.
An analysis of the concentration dependence of the optical densities of the bands in the decomposed spectra showed that in solutions with concentrations of water up to 2 M each water molecule binds two molecules of the acid. In more dilute solutions, mainly products of the interaction of water and the acid in a 1∶:1 ratio form.
