Neutralization-Reionization Mass Spectrometry (Chemistry)

该项目属于分析和表面化学的一般领域，以及质谱学的子领域。麦克拉弗蒂教授在他之前的美国国家科学基金会拨款(CHE-8406387)的支持下，开发了一种新的技术--中和-再电离质谱仪，用它可以制备和表征反应性中性气相物种。这个实验计划的目标是现在利用NRMS来基础研究反应性正离子和负离子在中和和再电离过程中的行为，并开发利用这种新的离子形成方法的分析质谱学技术。这项研究的结果将加深我们对高能中性分子行为的理解，这些分子可以用于通过等离子体和束流处理技术生产新材料，并可能导致新的分析质谱仪的发展。

This project is in the general area of analytical and surface chemistry and in the subfield of mass spectrometry. With the support of his previous NSF grant (CHE-8406387), Professor McLafferty has developed a new technique, neutralization- reionization mass spectrometry (NRMS), with which reactive neutral gas phase species can be prepared and characterized. The goal of this experimental program is to now exploit NRMS for the fundamental study of the behavior of reactive positive and negative ions in neutralization and reionization processes and to develop analytical mass spectrometric techniques which utilize this novel approach to ion formation. The results of this research should enhance our understanding of the behavior of energetic neutral molecules which can be used in the production of new materials by plasma and beam processing techniques and could give rise to the development of new instrumentation for analytical mass spectrometry.
