RAMAN INTENSITIES OF LIQUIDS - ABSOLUTE SCATTERING ACTIVITIES AND ELECTROOPTICAL PARAMETERS OF THE HALATE IONS CLO3-, BRO3-, AND IO3- IN AQUEOUS-SOLUTIONS

Absolute Raman scattering activities of aqueous solutions of sodium bromate and lithium iodate have been measured against NaClO4 as an external standard. Electro-optical parameters (EOPs) for the Br-O and I-O bonds were calculated. Equilibrium bond polarizabilities were estimated from refractive index measurements in connection with Raman intensities of the bending modes. Relations between Bragg-Slater radii and EOPs are discussed. EOPS calculated from experimental data are compared with those from ab initio calculations.
