The vibrational spectrum and the normal coordinate analysis of KOX (X H or D)

The Raman spectra of KOX (X H or D) at 77 K and room temperature are reported. The observed frequencies are assigned on the basis of a normal coordinate analysis by use of the valence force field. The KO stretching force constants are consistent with those expected from bond distances or related compounds. Dispersion relations are derived and some bands are assigned to a combination band at critical points.
