Molecular interactions in atenolol—ethanol mixtures: An ultrasonic study

In the present study ultrasonic velocity (υ), density (ρ), and viscosity (η) of the mixtures of atenolol drug with ethanol have been measured at frequency 1 MHz in the concentration range 0.1–0.0125% at 303, 308, and 313 K using multifrequency ultrasonic interferometer. The measured values have been used for calculations of the mixtures acoustical parameters. These parameters explained molecular interactions existing in the solution.
