Lattice vibration spectra. XII. IR, FIR, and Raman spectra of alkaline earth metal- and lead halide-monohydrates (in German)
The IR-absorption and reflection spectra and the Raman spectra of the halogenate monohydrates: Ba(ClO$sub 3$$)$$sub 2$ x H$sub 2$O, Pb(ClO$sub 3$$)$$sub 2$ x H$sub 2$O, Ca(BrO$sub 3$$)$$sub 2$ x H$sub 2$O, Sr(BrO$sub 3$$)$$sub 2$ x H$sub 2$O, Ba(BrO$sub 3$$)$$sub 2$ x H$sub 2$O, Pb(BrO$sub 3$$)$$sub 2$ x H$sub 2$O, and Ba(JO$sub 3$$)$$sub 2$ x H$sub 2$O as well as the deuterated and partial deuterated compounds are analysed in the range 4,000 - 30 cm$sup -1$ at temperatures from - 160 to +190$sup 0$C. The assignment of the vibrations to the species of the factor group were made by means of single crystal measurements. The large coupling of the internal vibrations of the halogenate ions causes a comparatively great factor group splitting. According to the OH stretching vibrations (or the OH force constants) and the anomalous temperature dependence of the internal vibrations of the H$sub 2$O molecules symmetric, but not linear hydrogen bridges exist in the halogenates of Ba(ClO$sub 3$$)$$sub 2$ x H$sub 2$O type, whose strength increases from chlorate to iodate. The hydrogen bridges of Ca(BrO$sub 3$$)$$sub 2$ x H$sub 2$O however are strongly asymmetric in consequence of the two OH and OD stretching vibrations of HDO in partial deuterated samples. (orig.)
