“…The increase of adiabatic compressibility (β) with increase in temperature might be due to molecular interaction in solution which supports solvent-solute interactions. The increase of adiabatic compressibility and linear free length for all system suggest breaking of hetero and homo association of molecules [23] .…”

Density, ultrasonic velocity of pure solvent, dimethylformamide (DMF) and ligand solutions of substituted thiazoles in DMF-water mixture were measured at different temperatures (303.15, 308.15, 313.15 and 318.15) K. Acoustical parameters such as adiabatic compressibility, intermolecular free length, acoustical impedance and relative association were determined from experimental data of density and ultrasonic velocity. The effect of temperature variations on the strength of molecular interaction has also been studied. An excellent correlation represents in terms of solute-solvent and solvent-solvent interaction at all temperatures.

Density, ultrasonic velocity of pure solvent, dimethylformamide (DMF) and ligand solutions of substituted thiazoles in DMF-water mixture were measured at different temperatures (303.15, 308.15, 313.15 and 318.15) K. Acoustical parameters such as adiabatic compressibility, intermolecular free length, acoustical impedance and relative association were determined from experimental data of density and ultrasonic velocity. The effect of temperature variations on the strength of molecular interaction has also been studied.

“…Owing to their various applications in various fields, it would be interesting to study their volumetric properties in solutions. In recent years, the ultrasonic, volumetric and viscometric techniques have gained much importance due to their ability of characterizing physiochemical behavior of liquid systems [31][32][33]. These parameters enable evaluation of some useful thermodynamic and transport parameters, which can be used to explain the nature and extent of molecular interactions qualitatively; because the properties of pure substances are different from their mixtures [34,35].…”

Measurement of ultrasonic velocity, density and viscosity of solutions of Tetra Butyl Ammonium Bromide have been carried outin different solvents (water, methanol, ethanol, 1-propanol and 1-butanol) as functions of concentration (1 to 0.1 M) at different temperatures (298.15 K to 318.15 K). Using these experimental data, various acoustical and apparent parameters such as acoustical impedance, intermolecular free length, adiabatic compressibility, molar compressibility, Van der Waals constant, relaxation strength, apparent molar isentropic compressibility, apparent molar volume have been evaluated. Further, some thermodynamic parameters such as Gibbs free energy of activation, enthalpy and entropy of activation have been evaluated. All these parameters have been evaluated to understand type of interactions present in studied solutions.
