he pH 11 spectrum for LiCl was missing, and the pH 10−6 spectra were shown to be 1 pH unit lower than the actual pH based on the color sequence shown in the Figure 1 legend. The properly color-coded LiCl spectra including the pH 11 spectrum are now shown in the revised Figure 1 below. Figure S1 in the Supporting Information has also been corrected to show the raw SFG spectra corresponding to the smoothed data displayed in the revised Figure 1. The revised Figure 1 and Figure S1 do not change the conclusions of the manuscript and are more consistent with the discussed trends.
