Temperature transformation of microwave dielectric spectra of Rochelle salt in the dynamic conductance model

Аннотация

The temperature transformation of submillimeter dielectric spectra of Rochelle salt is analyzed within the framework of dynamic conductance model. The branched network of hydrogen bonds and crystallization water molecules in Rochelle salt is supposed to form a quasi-localized vibrational mode in the crystal spectrum. This mode determines the resonant dielectric response at helium temperatures, which with an increase in temperature is transformed into the relaxation response of diffusion motion.
