Abstract
We have measured the dielectric permittivity of pure water and aqueous chlorides solutions in the range 0.2-1.5THz. Considered the relaxation spectral function as the weighted sum of two independent single-parameter Debye functions [1] we have been able to drastically reduce the number of the parameters used in the fit. The experimental data in the THz range for pure water and solutions of LiCl, KCl, NaCl, and CsCl are very well reproduced by the linear combination of two single-parameter Debye function [2].I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
