Abstract :
We measured the dynamics of aqueous biomaterial mixtures using terahertz time-domain spectroscopy. The mixtures were divided into water and other electrolyte parts in mass fractions for analysis. The optical constants of the electrolytes, excluding water, were obtained by applying the ideal mixture equation and fitted with the modified double Debye model. We found that the reorientation and hydrogen-bond formation-decomposition times decreased as the electrolyte concentration increased.
