Figure 5. Example of fitting of b- (green) + q-dimer (grey) model spectra to the experimental continuum, obtained in this work at different temperatures. The resulting total model (sum of b- and q-dimer) absorption is shown in red. For more accurate fitting, the wavenumbers of stable WD transition at 3597 and 3730 cm–1 [12] were shifted to 3616 and 3717 cm–1 respectively. The νi(PA) and νi(PD) on the top panels denote respectively proton-acceptor and proton-donor H2O unit in WD, while i = 1,2,3 mean correspondingly symmetric stretching, bending, and asymmetric stretching oscillations in the water unit. The values of Kq and Kb (in atm–1) that lead to a best fit are shown in the legends of each frame. (For interpretation of the references to colour in this figure legend, the reader is referred to the web version of this article.)
