From experimental data of density, viscosity and ultrasonic velocity, the various acoustical properties, such as specific impedance ( Z ), isentropic compressibility ( κ s ), Rao's molar sound function ( R m ), the van der Waals constant ( b ), molar compressibility ( W ), intermolecular free length ( L f ), relaxation strength ( r ), internal pressure ( π ), free volume ( V f ), solvation number ( S n ) etc ., were calculated for three Schiff bases in 1,4‐dioxane and dimethylformamide (DMF) at 318.15 K. The results are interpreted in terms of molecular interactions occurring in the solutions.
