Paper Abstract

Recent developments in far infrared, laser spectrometry and dispersive Fourier transform spectrometry have allowed the direct determination of the optical constants of some aqueous salt solutions in the spectral range between 25 and 450 cm-1. The following salts were studied by these methods LiC1, LiC1O4, NaCl, NaC1O4, NaI , KCl, Kbr, KI, KF, MgCl2, Mg(ClO4)2 and Bu4NBr (tetrabutylammonium). The results show that in the presence of some electrolytes the optical constants of the solution can differ significantly from those of pure water, and that in localised spectral regions the absorption can be many times less than that of pure water.
