Vibrational investigation of the stretching region of bromate ion in solution.
The splitting of v1 (794 cm(-1)) and v3 (805 cm(-1)) modes in the stretching region of the bromate (C3v) was observed for the first time in dimethyl sulfoxide (DMSO) using vibrational spectroscopy. Depolarization measurements allowed to assign the asymmetric and symmetric modes in solution. The band at 805 cm(-1) that has been attributed to the symmetric stretching mode (A1) corresponds in fact to the asymmetric stretching mode (E) and the band at 794 cm(-1) corresponds to the symmetric stretching mode (A1).
