Electron-Ion Recombination Chemistry: Determination of Fragmentation and Product Distributions

在这个由化学系实验物理化学项目资助的项目中，亚当斯将开发一种独立的技术来确定解离的电子-离子复合速率和产物分布。该方法的目的是规避困难，造成矛盾的结果，从以前的研究流动余辉和存储环实验。在对已被充分理解的系统进行初步测试后，该技术将应用于文献中报告了有争议结果的系统。将研究解离复合起主要作用的新系统。星际和彗星气体以及地球高层和低层大气的分子不断地经历解离电离，然后再复合。 的重组率以及解离产物的分布是实验确定的，并提供理论建模的基础。用于确定这些参数的常规方法通常给出不同的结果。该项目旨在开发一种新的方法来生成可靠的数据，用于测试现有的理论和开发新的理论。这项工作将在研究生、本科生和博士后研究人员的协助下进行。在这个由化学系实验物理化学计划资助的项目中，亚当斯将开发一种独立的技术来确定解离的电子-离子复合速率和产物分布。该方法的目的是规避困难，造成矛盾的结果，从以前的研究流动余辉和存储环实验。在对已被充分理解的系统进行初步测试后，该技术将应用于文献中报告了有争议结果的系统。将研究解离复合起主要作用的新系统。地球高层和低层大气中的星际和彗星气体分子不断地经历解离电离，然后再复合。 的重组率以及解离产物的分布是实验确定的，并提供理论建模的基础。用于确定这些参数的常规方法通常给出不同的结果。该项目旨在开发一种新的方法来生成可靠的数据，用于测试现有的理论和开发新的理论。这项工作将在研究生和本科生以及博士后研究助理的协助下进行。

In this project, funded by the Experimental Physical Chemistry Program of the Chemistry Division, Adams will develop an independent technique to determine dissociative electron-ion recombination rates and product distributions. The method is designed to circumvent difficulties that have caused contradictory results from previous studies with flowing-afterglow and storage ring experiments. After initial tests on well understood systems, the technique will be applied to those for which controversial results have been reported in the literature. New systems where dissociative recombination plays a major role will be investigated.The molecules of interstellar and cometary gases, and of the earth's upper as well as lower atmosphere, continually undergo dissociative ionization followed by recombination. The rates of recombination as well distributions of the dissociation products are experimentally determined and provide the basis for theoretical modeling. Conventional methods for determining these parameters have often given disparate results. This project is designed to develop a new method to generate reliable data for testing of existing theories and the development of new ones. The work will be performed with the assistance of graduate and undergraduate students and postdoctoral research associates.In this project, funded by the Experimental Physical Chemistry Program of the Chemistry Division, Adams will develop an independent technique to determine dissociative electron-ion recombination rates and product distributions.
