As part of our studies on the nature of interactions in aqueous electrolyte solutions and in molten salts, we have investigated the Raman spectrum of $Ca(NO_{3})_{2}$ $4H_{2}O-KNO_{3}$ mixtures (up to 70 mole % $KNO_{3}$). The spectra were recorded with a Jarrell-Ash Laser-Raman spect rometer using $He-$Ne and $Ar^{+}$ion lasers as exciting sources. Results are reported for the band shape variations (intensity and polarization) as a function of concentration, relative to the $\nu_{3}$ and $\nu_{4}$ regions of the $NO_{3}^{-}$ion spectrum and the ($3000-3600 cm^{-1}$) water band region and discussed from current viewpoints of ionic interactions and water structure. en_US dc.format.extent 104531 bytes dc.format.mimetype image/jpeg dc.language.iso English en_US dc.publisher Ohio State University en_US dc.title RAMAN SPECTRAL INVESTIGATIONS OF $Ca(NO_{3})_{2}.4H_{2}O-KNO_{3}$ MIX TURES en_US dc.type article en_US
