Polyselenides and their radical ions
- Argonne National Lab., IL (United States); and others
Several polyselenides, Se{sub n}{sup 2-} (n=2-4), were synthesized in aqueous solutions by oxidation of hydrogen selenide with hydrogen peroxide. Both absorption and Raman spectra were recorded and the observed bands were assigned to the various species and their vibrational modes. Additionally, single-electron reduction and oxidation radical ion products were generated in solution by reaction with e{sup -}{sub aq} and OH radicals, respectively, using the pulse radiolysis technique. Spectra of these products, as well as their formation and decay dynamics, were recorded and will be discussed. Ab initio electronic structure and vibrational mode calculations were conducted and the results were compared with experimental observations.
