The solute capability of bond transition in terms of the fraction coefficient, follows the relation, f<ce:inf loc="post">NaX</ce:inf>(C)∝1-exp(?C/C<ce:inf loc="post">0</ce:inf>) towards saturation, with C being the solute concentration and C<ce:inf loc="post">0</ce:inf>the decay constant. Observations evidence that: (i) the solute ionic field electrification aligns, stretches, and polarizes its neighboring H<ce:inf loc="post">2</ce:inf>O molecules, which shortens the HO bond but lengthens the O:H nonbond via OO Coulomb repulsion; (ii) the effect of X<ce:sup loc="post">?</ce:sup>electrification on the O:HO bond relaxation varies with solute type and solute concentration. Exercises not only verify the essentiality of solvent O:HO bond cooperative relaxation and polarization but also demonstrate the power of DPS that resolves processes occurred upon solvation.</ce:simple-para></ce:abstract-sec></ce:abstract><ce:abstract xmlns:ce="http://www.elsevier.com/xml/common/dtd" xmlns="http://www.elsevier.com/xml/ja/dtd" id="ab0010" class="graphical" xml:lang="en" view="all"><ce:section-title id="st0010">Graphical abstract</ce:section-title><ce:abstract-sec id="as0010" view="all"><ce:simple-para>Display Omitted</ce:simple-para></ce:abstract-sec></ 收起
