The resonance Raman spectra of tris(2,2′-bipyrazine)ruthenium(II) complex, Ru(bpz), were obtained in solutions of H2SO4-H2O and 2H2SO4-2H2O at acid concentrations between 0 and 98 wt.%. The spectral results are consistent with sequential protonation (or deuteration) of the six ...
The chemical structures of the synthesized compounds were confirmed using infrared spectroscopy (IR), proton (1H) nuclear magnetic resonance (NMR), and mass spectrometric analysis.Bouguessa, IchrakDehamchia, MohamedBayou, SamirGouasmia, Abdelkrim...
Electron Spin Resonance Studies of Aliphatic Ammonium Ion Radicals in Aqueous Sulfuric Acid GlassesThe reaction of hydrogen atoms with n-butylammonium ions in 6 M sulfuric acid glasses yields a characteristic eight-line e.s.r. spectrum, which is attributable to CH3HCH2CH2NH3+. Evidence is drawn ...
