The intensities of the intra-solute C-C/C-O and S-C/S=O bonding vibrations increase as the concentration of organics increases. To trace the relaxation of the dominate HB in the organicwater mixtures, it would suffice for one to focus on the H-O stretching vibration at 3000-3700 and However, one can hardly resolve how the individual bond of the hydrating system relaxes upon increasing the solute/solvent concentration from the full-frequency Raman spectra. The PDPS is proven one of the most efficient means for distilling relaxation information of the individual type of bonds in responding to a load of perturbation. The PDPS proceeds simply by subtracting the referential spectral peak of pristine water from those collected from the concentrated solutions upon all the spectral peaks being normalized. The PDPS peak features the transition of the phonon abundance (peak area), bond stiffness (frequency shift), and structure order (peak width) from the vibration mode of pristine water to the concentrated hydration interfaces. The extent of the segmental frequency shift depends on the relative polarity and the solute/solvent ratio.
