Infrared and Raman Spectroscopic and Force Field Studies of Y(H2O)9(BrO3)3


Infrared and Raman spectra of the nonaaqua yttrium(III) bromate, Y(H2O)9(BrO3)3, compound have been recorded. Force field calculations have been performed for YO93+ moiety, with a tricapped trigonal prismatic oxygen atom arrangement in D3h point group symmetry. The larger stretching force constant was found, 90.7 Nm-1, for the Y-O prism in comparison with the corresponding value in the capped Y-O, 56.5 Nm-1.
