The ultrasonic absorption for binary liquid systems, water-Triethylamin and water-Methylethylketon which have the lower critical solution temperature, is measured by the pulse technique at the frequeucies 0.98, 1.98, 3.00MC. Similar to the solution with upper critical temperature, the contribution of clusters to remarkable absorption is the greatest at the concentration for which the solubility curve shows minimum and becomes smaller as the temperature tends away from the critical point, and the relaxation frequencies seem to be as low as those of the solution with upper critical temperature.
