Water Structure, Quantum Nature of Hydrogen Bonds and Diffusion of Water Molecules in Chloride Aqueous Solutions

摘要: A large variety of water properties is caused by the peculiarities clusters and hydrogen bonds which are quantum mechanical in nature due to a small mass atoms. The concentration dependences diffusion coefficient D for aqueous solutions were found using DOSY 2D NMR method. It was shown that with exception barium chloride solution, exhibits an anomalous behavior range 0–10 mg/ml, two other decreases increasing concentration. On basis generalized Stokes–Einstein equation following correlation lengths \( c = 100 \) mg/ml obtained: \left\langle \xi \right\rangle_{{H_{2} O}} {\kern 1pt} 1.0 7 A, \right\rangle_{{MgCl_{2} }} 0. 9 3 \right\rangle_{{CaCl_{2} 1.04 \right\rangle_{{BaCl_{2} 8 4 A.
