Ultrasonic attenuation spectrometry study of α-cyclodextrin + KI complexation in water

Excess-attenuation-per-wavelength spectra for 0.1 mol/l aqueous solutions of α-CD at 25 °C without (
- ) and with KI added (▴; cKI = 0.15 mol/l,▾; cKI = 0.15 mol/'). Dashed and dotted lines indicate the subdivision of the spectra in two Debye type relaxation terms. Full curves represent the relaxation spectral functions.
