Molecular Interactions in DMF Solutions of some Pyrazole Schiff Bases at 308.15 K

Author: Shipra Baluja, Jayesh Javiya

Category: Research Article


The density, ultrasonic velocity and viscosity of solutions of pyrazole Schiff bases in dimethyl formamide have been measured at 308.15 K. From the experimental data, various acoustical parameters such as specific Impedance, isentropic compressibility, Rao’s molar sound function, Van der Waals constant, relaxation strength, intermolecular free length, internal pressure, solvation number, relative association etc. have been evaluated, which helps in understanding the molecular interactions occurring in these solutions.
