Acoustic, FTIR and Raman spectroscopic studies of aspartame and citric acid

To study the molecular interactions between artificial sweetener and edible acid Ultrasonics, Material Science To determine the molecular interactions between artificial sweetener and edible acids using acoustical parameters Acoustical parameters, spectroscopy and stability constant The molecular interactions and functional groups that are present is found As the concentration increases, acoustical parameters like ultrasonic velocity, viscosity, density, Relaxation time, acoustic impedance while, other acoustical parameters like adiabatic compressibility and intermolecular free length decreases with the increases with concentration. This proves that there is a strong interaction between solute and solvent. Spectroscopy Experimental Study
