In second part of this work, velocity and absorption measurements of ultrasonic waves in aqueous solutions of ß-cyclodextrin containing different sodium alkyl sulfates are reported. One or two relaxation processes for these solutions have been established. Thermodynamic and kinetic parameters related to these processes have been calculated. The results have been compared with those obtained for solutions of ?-cyclodextrin and presented in Part 1 of this paper. Explanation of the origins of these processes has been proposed.
