Electrical conductance (10-5 to 1 M) at 25, -15, and -30° and ultrasonic absorption (0.05-0.5 M) in the frequency range 5-330 MHz at 25, -15, and -30° have been measured for LiClO4 in tetrahydrofuran (THF). The electrical conductance data reveal the presence of a minimum that can be interpreted and evaluated by the Fuoss-Kraus theory of triple ion formation (up to ∼0.1 M). Numerical evaluation of ion pair and triple ion pair constants were made. The ultrasonic relaxation data are interpreted as due to the process of formation of triple ions, the barrier of activation energy for the process being comparable to the one for viscous flow.
