Densities and ultrasonic velocities of these compounds have been measured over the wide composition range at 313.15 K in Dimethylformamide (DMF) and Tetrahydrofuran (THF). From these experimental data, various acoustical and thermodynamic parameters were evaluated. Some of these parameters are isentropic  compressibility (s), intermolecular free length (Lf), solvation number (Sn), relaxation strength (r), internal pressure (), free volume (Vf), Rao's molar constant (Rm), Vander Waals constant (b), molar compressibility (W) etc. The types of interactions in solutions of these compounds in DMF and THF are explained from the evaluated parameters.                https://journalofchemistry.org/paper/650/ Schiff bases Ultrasonic Study Acoustical Parameters DMF THF
