  The HOO complex with SO2, a matrix isolation study

  摘要：

  The complex formation between HOO and SO2 in argon,matrices has been studied with FTIR spectroscopy. The complex shifts of the intramolecular fundamentals of the complex components suggest the formation of a complex, where HOO acts as a lone pair donor to the sulfur atom of SO2 while its hydrogen atom is sufficiently close to one of the oxygen atoms of SO2 to give a significant blue shift of the HOO bend. The complex is rapidly decomposed by irradiation at 266 nm. A comparison between the spectrum of the photoproduct and the spectrum of matrix isolated sulfuric acid suggests the possibility that the photoproduct is the radical formed by dissociation of one of the OH bonds of sulfuric acid.

• Time resolved resonance Raman observation of the extreme protonation forms of a radical zwitterion in water
  作者：G. N. R. Tripathi

  DOI：10.1063/1.1860311

  日期：2005.2.15

  p-aminophenoxyl radical in strongly basic to extremely acidic aqueous solutions have been investigated using time-resolved resonance Raman spectroscopy. The dynamic stability of the different protonation forms of the radical, observed on the microsecond time scale in this work, has been achieved by controlling the proton exchange rate in water. In strongly acidic solutions we observe a rare ring-H+ bonded dication

  使用时间分辨共振拉曼光谱研究了质子水溶液与两性离子对氨基苯氧基在强碱性至强酸性水溶液中的反应。通过控制水中的质子交换速率，可以在微秒级的时间范围内观察到自由基的不同质子化形式的动态稳定性。在强酸性溶液中，我们观察到稀有的环-H +键合指示性物质，这是胺水解的关键中间体。中性对氨基苯氧基自由基在强碱性水溶液中经历NH2-去质子化作用，而在封闭壳胺中没有类似物。
