Matrix and Gas Phase Reactions of XNO (where X = F, Cl or Br)

主要研究者提议启动一项研究项目 其目标如下： a）鉴定ClNO与NH3之间的反应的最终产物， (XNO)和其他大气物质，特别是臭氧，水， 硫氧化物和简单烯烃，以及它们与 大气化学 B）获得关于这些反应的时间尺度的信息， 发生. c）通过使用以下方法对反应机理提供一些见解： 基质隔离技术。 d）确定是否观察到振动诱导的化学反应 在XNO反应，并研究这些机制， 发生红外诱导反应。 将开展的初步活动 在规划期间完成的工作包括： 1)亚硝酰卤与臭氧的合成。 2)设计和建造一个真空系统， 反应物的制备 3)修改低温恒温器的设计以制备干净的基质 并允许将样品从FT-IR运输到 紫外-可见光谱仪 4)调整部门FT-IR以适应低温恒温器 5)修改实验室空间以提供足够的空间 电气要求、水要求和通风 用于真空设备。

The principal investigator proposes to initiate a research project with the following goals: a) to identify the final products of the reactions between ClNO (XNO) and other atmospheric species, in particular ozone, water, sulfur oxides and simple alkenes, and their relevance to atmospheric chemistry b) to obtain information on the time scales in which these reactions occur. c) to provide some insight into the reaction mechanisms by use of matrix isolation techniques. d) to determine whether vibrationally induced chemistry is observed in XNO reactions and investigate the mechanisms by which these infrared induced reactions occur. Preliminary activities to be done during the planning period include the following: 1) Synthesis of the nitrosyl halides and ozone. 2) Design and construction of a vacuum system that will allow the preparation of the reactants 3) Modify the designs of a cryostat to prepare clean matrices and to allow the transportation of samples from the FT-IR to the UV-Vis spectrometer. 4) Adaptation of the departmental FT-IR to fit the cryostat 5) Modification of laboratory space so as to provide adequate electrical requirements, water requirements, and ventilation for the vacuum equipment.
