title: Temperature dependences of the acoustic nonlinearity parameter B/A of aqueous solutions of amino acids.
abstract: A differential technique for evaluating the molar increments of the nonlinearity parameter B/A has been employed for investigations of aqueous solutions of the amino acids glycine, alanine, norvaline, norleucine, arginine monohydrochloride, and lysine monohydrochloride in the temperature range 18 degrees C-45 degrees C. Some regularities of temperature dependencies of the nonlinearity parameter B/A of hydration shells of charged and aliphatic groups have been found. Contributions of these groups to the value of B/A molar increments of solute versus temperature have been estimated.
