In this part, the velocity and absorption measurements of
ultrasonic waves in aqueous solutions of [ampersand]alpha;-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. In the second part,
experimental results for [ampersand]beta;-cyclodextrin will be reported and compared with
those presented here.
Keywords: cyclodextrins; surfactants; ultrasonic spectroscopy; relaxation processes
