The hydration equilibrium of amide C=O, which had been reached at the time of mixing with water particles, should be rearranged to dissolved water in the new surroundings at the time of measurement. As the hydration ability is stronger, residence time of hydration is longer, and the quantity of the "free and dissociated" water in the solution may not be sufficient to satisfy the high hydration ability of amide C=O to equilibrium at lower concentrations, because dissociated water may partly phase out of solution.

    • -1 region (see ref 30 and 33). The water dissolved in all the other liquids shows clearly separate two bands in the frequency region, which are definitely assigned to antisymmetric and symmetric OH stretching vibrations. The absorption of the water in heptane is considerably weaker than those in the other liquids.
