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

首席调查员提议启动一项研究项目，目标如下：a)确定ClNO(XNO)与其他大气物种，特别是臭氧、水、硫氧化物和单烯之间反应的最终产物，以及它们与大气化学的相关性，b)获得关于这些反应发生的时间尺度的信息。C)通过使用基质分离技术提供对反应机理的一些见解。D)确定在XNO反应中是否观察到振动诱导化学反应，并研究这些红外诱导反应发生的机制。计划期间要开展的初步活动包括：1)合成硝基卤化物和臭氧。2)设计和建造真空系统，允许制备反应物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传输到UV-Vis光谱仪。4)调整部门的FT-IR以适应低温恒温器5)修改实验室空间，以便为真空设备提供足够的电力要求、水要求和通风。

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.
