Abstract

The acoustical parameters of glycine, α-alanine and β-alanine have been measured in aqueous and aqueous D-Glucose solutions at 298.15K. The molar sound velocity (R), molar compressibility (W), freelength (Lf), freevolume (Vf), internal pressure (πi), relaxation time (τ), ultrasonic attenuation (α/f2) and Van der-Waals constant (b) values have been calculated from the experimental data. These parameters are used to discuss the molecular interactions in the solutions.
