Acoustical Studies of Some Derivatives of 1,5-Benzodiazepines at 298.15 K

Some new derivatives of 1,5-Benzodiazepines have been synthesized and their structural characterizations are done by IR, NMR and Mass Spectral data. The ultrasonic velocity, density and viscosity of these synthesized compounds have been measured in dimethyl formamide and tetrahydrofuran at 298.15 K. From these experimental data, some acoustical parameters such as isentropic compressibility, intermolecular free path length, Rao’s molar sound function, relaxation strength, solvation number etc., have been calculated which helps in understanding the molecular interactions occurring in these solutions.
