Аннотация
Experimental results for the absorption of ultrasonic waves in pure cyclohexanol and aqueous solution of cyclohexanol in the frequency range 0.06–150 MHz and at temperatures 30, 40, 50, and 60 °C are reported. The ultrasonic relaxation spectra of pure cyclohexanol investigated show two relaxation processes in contrast to those aqueous solutions of cyclohexanol, which indicate a single relaxation process. One relaxation process is located in the frequency range 0.01–1 MHz and the second in the range 0.8–10 GHz. The process with the lower relaxation frequency has been assigned to the “chair”–“chair” molecular conformations.
