Development of Tandem Sector and Fourier Transform Mass Spectrometries for Ion Chemistry and Structure Determination

该项目在分析和表面化学的一般领域，侧重于质谱分析。重点将放在离子化学上。这项工作有望带来新的仪器功能，这将推动质谱分析的应用，并提供对离子化学的更好理解。工作将集中在质谱中与电荷远程破碎有关的四个方面，即能量学、机理、向新型反应的扩展以及在电荷远程化学中产生的中性物质的鉴定。离子化学的研究将包括自由基阳离子化学，小无机离子的电离势的研究，以及负离子的醛型反应。与离子化学有关的仪器开发的一些方面将被检查。特别是傅立叶变换质谱（FTMS）离子阱的研究。

The project, in the general area of Analytical and Surface Chemistry, focuses on mass spectrometry. The principal emphasis will be on ion chemistry. The work promises to lead to new instrumental features which will advance the analytical application of mass spectrometry and also provide a better understanding of ion chemistry. The work will focus on four areas related to charge-remote fragmentation in mass spectrometry, namely energetics, mechanism, extension to new types of reactions, and identification of neutrals produced in charge-remote chemistry. Ion chemistry studies will include radical cation chemistry, the study of ionization potentials of small inorganic ions, and aldol-type reactions of negative ions. Some aspects of instrumental development will be examined that relate to ion chemistry. In particular, work will be carried out on Fourier transform mass spectrometry (FTMS) ion traps.
