Photoprocesses and Chemical Kinetics in the Excimer Molecules (REU Supplement)

研究对各种等离子体过程具有重要意义的电子激发物质的动力学是先前热系统计划奖的延续。研究的领域是光结合产生的准分子的化学性质，以及激发态原子间电位在猝灭中的应用。具体来说，光关联将用于研究浅或预解离准分子状态的结构，或具有解离基态的更强结合的电子激发分子的化学反应性。这种方法使人们能够从真空紫外线中接触到难以通过实验研究的物种。为了研究原子相互作用势对原子激发态碰撞失活的影响，本文将对异核双原子稀有气体系统进行激光里德堡光谱分析。期望该实验方案能够提供难以观测到的原子和准分子的基本化学和光学数据，并提高我们对具有工程意义的器件和过程的理解和性能。

Research into the kinetics of electronically excited species of importance to a variety of plasma processes is proposed in a continuation of a previous Thermal Systems Program award. The areas to be investigated are the chemical properties of excimers produced by photoassociation, and the application of excited state interatomic potentials to quenching. Specifically, photoassociation will be utilized to investigate the structure of shallow or predissociating excimer states or the chemical reactivity of more strongly bound electronically excited molecules having dissociative ground states. Such an approach allows one to access species from the vacuum uv that are otherwise difficult to study experimentally. Laser inter- Rydberg spectroscopy of heteronuclear diatomic rare gas systems will be conducted in order to investigate the impact of atomic interaction potentials on the collisional deactivation of atomic excited states. It is expected that the experimental program will provide fundamental chemical and optical data concerning difficult to observe atomic and excimer species, and that the results will improve our understanding and performance of devices and processes of engineering significance.
