Description :
In the present study, ultrasonic velocity (u), density (ρ) and viscosity (η) have been measured at 2 MHz frequency in the binary mixtures of Riboflavin with methanol in the concentration range (0 to 0.1 M) at 303K using Ultrasonic interferometer technique. The measured value of ultrasonic velocity, density and viscosity have been used to estimate the acoustical parameters namely adiabatic compressibility (βa), relaxation time (τ) and free length (Lf), with a view to investigate the nature and strength of molecular interaction in the binary mixture of Riboflavin with methanol. The obtained result support the occurrence of Complex formation through intermolecular hydrogen bonding in these binary liquid mixtures.
