Vibrational spectra of some Group Vb halides. III. A far-infrared and Raman spectral study of some Hexahalogeno-, Pentahalogeno-, and Tetrahalogeno-bismuthate(III) and -antimonate(III) salts

Abstract

Vibrational spectra of a series of halogeno-complex ions of antimony(III) and bismuth(III) are reported. Results of crystal spectra are discussed in terms of the structural environment and a comparative study of Raman solution and solid state spectra is given. Some force constants for hexahalogeno species on a modified Urey-Bradley force field have been calculated and their significance is discussed.
