Abstract
Ultrasonic absorption and velocity measurements over the frequency range 1 to 10 MHz at 303 K on mixtures of n-hexane and perfluoro-n-hexane confirm the existence of a rotational isomeric relaxation in the perfluoro-compound, and give evidence of a structural relaxation in the liquid mixtures. This last process occurs at frequencies much higher than those associated with conformational change and its amplitude can be predicted from the excess thermodynamic quantities of mixing.Keywords
