Other Sulfur and Selenium Compounds

3 Other Sulfur and Selenium Compounds. - The high-pressure Raman spectrum of D2S gave evidence for dissociation to sulfur at pressures above 27 GPa at room temperature. A normal coordinate analysis for crystalline H2S and D2S gave good agreement with experimental data.  

Ab initio calculations of vibrational wavenumbers were reported for clusters S04 (H20) , where n = 1-6, and used to analyse data on aqueous solutions of 804 . Raman data show that the reaction of NaCl with H2SO4 produces only NaHS04. ° IR data have been reported for S04 ions isolated in an Ag2Se04 matrix.  

Raman spectroscopy was used to characterise sulfate species in borosilicate glasses designed for radioactive waste storage. Similar measurements were used to probe the structures of concentrated aqueous solutions of H2SO4 (81-100% H2SO4). A high-resolution study of the V4 band of SFe shows that the band origin is at 614.98196(15) cm  

A high-resolution FTIR emission spectrum of the radical SeH (X f7 ground state) showed that cOe was at 2421.7153(234) cm , and 00eX 44.6012(110) cm . Band origins were also measured for HDSe in the 2v2 and 2v3 regions. Table 18 summarises the assignments for the Vi bands for D2 Se, where M = 76, 77, 78, 80, 82.
