In our previous investigation, we have revealed that the electric field shorten and stiffen the H-O bond while the weaker O:H nonbond does the contrast, associated with polarization due to O:H-O bond cooperativity and polarizability (Figure ). The inhomogeneous charge distribution of a organic molecule is expect to generate a dipole electric field, which exerts the similar polarization effect to the direct-current electric field on the adjacent water molecules (Figure ).
