Atmospheric Ozone Chemistry

我们对大气化学理解的最新进展清楚地表明，关于臭氧及其光解离产物O(1D2)和O2(X3E-g)的关键过程的可靠光化学和动力学信息的重要性。这项提议涉及臭氧的紫外光分解导致这些活性物种的产生的效率以及它们在与环境分子(包括H2O、HCl和臭氧本身)碰撞时的后续命运的具体问题。特别强调开发可靠的光谱工具用于超微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。总而言之，这些实验将产生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种的能力。

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.//
