The acoustical parameters of glycine have been measured in aqueous solutions of sodium benzoate(SB), sodium bromide (SBr), and nicotinamide (N) at 298.15K. The molar sound velocity (R), molar compressibility (W), Free length (Lf), free volume (Vf), internal pressure (pi), relaxation time (t), ultrasonic attenuation (a/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 solutionsKeywords

The acoustical parameters of glycine have been measured in aqueous solutions of surfactants, such as sodium cetrimide, sodium dodecylsulphate(SDS), and Triton-X(100) (TX-100) at 298.15K. The molar sound velocity (R), molar compressibility (W), free length (L<SUB>f</SUB>), free volume (V<SUB>f</SUB>), internal pressure (π), relaxation time (π), ultrasonic attenuation (a/f<SUP>2</SUP>), 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.Keywords

The acoustical parameters of glycine, α-alanine and β-alanine have been measured in aqueous and aqueous DGlucose 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.
