Atmospheric Ozone Chemistry

最近我们对大气化学的理解的进展已经清楚地表明，在涉及臭氧及其光解产物O（1D2）和O2（X3E-g）的关键过程中，可靠的光化学和动力学信息的重要性。该提案解决了一些具体问题，包括臭氧的紫外光解导致这些活性物质产生的效率，以及它们在与周围分子（包括H2O， HCL和O3本身）碰撞时的后续命运。特别强调的是开发可靠的光谱工具，用于超痕量检测反应和光解的高能产物；从拟议的研究中获得的信息将提供关于OH（A - X）和O2（B - X）转变的全新信息。这些实验将提供有关臭氧产生和消耗的化学机制的新信息，并扩大我们探测大气中化学不稳定物质的能力。//

Recent advances in our understanding of atmospheric chemistry have made clear the importance of reliable photochemical and kinetic information regarding critical processes involving ozone and its photodissociation products, O(1D2) and O2(X3E-g). This proposal addresses specific questions concerning the efficiency with which uvphotolysis of O3 leads to the production of these reactive species and their subsequent fate during collisions with ambient molecules including H2O, HCL, and O3, itself. Special emphasis is placed on the development of reliable spectroscopic tools for the ultratrace detection of the energetic products of reaction and photodissociation; the information obtained from the proposed studies will provide entirely novel information concerning the OH(A - X) and O2(B - X) transitions. Together these experiments will yield new information concerning the chemical mechanisms of ozone production and depletion, and extend our ability to detect chemically labile species in the atmosphere.//
