 Title: RAMAN SPECTRAL STUDIES OF AQUEOUS SOLUTIONS OF SELENIOUS ACID Creators: Walrapen, G. E. Issue Date: 1961 Publisher: Ohio State University Abstract: Raman spectra of aqueous solutions of selenious acid, and of strongly alkaline and partially neutralized aqueous mixtures of sodium hydroxide and selenious acid, have yielded the principal lines of the species $H_{2}SeO_{3}, SeO_{3}{^{2-}}$ and $HSeO_{3}{^{-}}$, respectively. In aqueous solutions of selenious acid, the intensities of two strong characteristic lines of $H_{2}SeO_{3}$ were found to be linear functions of the stoichiometric concentration. This fact indicates completeness in the reaction of $SeO_{3}{^{2-}}$ with water, and negligible dissociation of $H_{2}SeO_{2}$ into its ions, in the range of compositions studied. Some provisional vibrational assignments, of Raman lines of $SeO_{3}{^{2-}}$, and of $HSeO_{3}{^{-}}$ and $H_{2}SeO_{3}$ have been made, and those species have been considered in terms of the symmetry groups $C_{3\nu}$; and $C_{3-}$ Description: Author Institution: Bell Telephone Laboratories, Inc.
