✦ Synopsis
Ultrasonic relaxation spectra of LiC104 plus the open chain polyether triglyme (TG) at CLiCl04 = 0.8 M, molar ratio R = [TG]/[LiC104] = 1, and at temperatures of 15, 25, 35, and 45°C in dry acetonitrile are reported. Corresponding spectra for LiC104 plus the macrocycle 12-crown-4 (12C4) at R = [12C4]/[LiC104] = 1, at 10, 15, 20, 25, 30, and 40"C, and CL,C~W = 0.32 M in acetonitrile are also reported.
Both relaxation envelopes, for the two systems, have been fitted by two Debye relaxation processes and interpreted by the Eigen-Winkler reaction scheme:
