Proton Magnetic Resonance Study of Barium Bromate Monohydrate

The proton magnetic resonance absorption spectrum of barium bromate monohydrate was obtained using a Pound-Watkins spectrometer. Results indicate that there is only one orientation of the water molecule in the crystal. The p—p distance is 1.61±0.01 A and direction angles of the p—p vector are α0=30°, β0=95°, and γ0=122°. The experimental errors in these angles were ±3°. Apparently the water molecule is oriented so as to form the complex, OII Br——H–O–H——OII Br, where OBr are neighboring bromate oxygens. Results obtained for barium chlorate monohydrate were consistent with those for barium bromate monohydrate.
