Ultrasonic Velocity and Density were measured in six aqueous amino acids namely, L-Alanine, L-AsparticAcid, L-GlutamicAcid, L-Glutamine, L-Phenylalanine and L-Valine of different concentration at 303.15 K. The intermolecular free length and adiabatic compressibility are determined with experimentally measured ultrasonic velocity, and density and correlate them with molecular interaction in aqueous amino acids at 303.15K. The intermolecular free length is discussed in terms of weak interaction between unlike molecules.
