Abstract :
We have determined the complex dielectric constant of water and heavy water in the range from 0.2 to 3.5 THz from 269 to 362 K by employing THz time-domain attenuated total reflection spectroscopy. We find the THz component can be assigned not only to the Debye relaxation but also a vibration mode, which is found in other complimentary experiments.
