Fourier transform Raman and infrared spectra and normal coordinate analysis of organo-arsenic(III), -antimony(III) and -bismuth(III) thiolates

The FT-Raman and infrared spectra of (PhS)BiPh2, (PhS)(2)BiPh, (PhS)(3)Bi, (PhS)(3)Sb, (PhS)(3)As and (PhSe)BiPh2 were measured in the range 3600-100 cm (-1). A normal coordinate analysis was performed for all substances in t erms of the calculation and discussion of the force constants which are dep endent on the element-sulphur and element-selenium group using a modified v alence force field. Furthermore, for all compounds H-1-NMR, C-13-NMR and MS data were also given. The investigation of the microbiological activity of some substances against Escherichia coli was an additional aspect because of their strong bactericidal and fungicidal effects.
