STUDIES OF UNUSUAL REACTIVE SPECIES BY ION TRAP AND FTMS

这个子项目是许多研究子项目中利用 资源由NIH/NCRR资助的中心拨款提供。子项目和 调查员(PI)可能从NIH的另一个来源获得了主要资金， 并因此可以在其他清晰的条目中表示。列出的机构是 该中心不一定是调查人员的机构。 这项研究计划的长期目标是：1)学习如何将有机化学的机械论思想扩展到处理整个元素周期表中共价键的形成和断裂。2)利用通过研究活性中间体和反应机理所获得的知识来制造新分子、新类型的键和新材料。我们采取的方法是研究原子、分子和离子的反应，这些原子、分子和离子小到足以通过光谱测量进行很好的表征，并服从于理论和实验处理。我们研究了含缺电子基团XIV原子的高活性短寿命物种的化学，包括卡宾、碳阳离子CC和CH、硅基自由基RSI、硅烯RSI：、硅烯RSI=CR、硅正离子SiH、锗、RGe：、香烯RGE=CR、膦系R-P以及自由原子C、Si和Ge。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. The long-range goals of the this research program are 1) To learn how the mechanistic ideas of organic chemistry can be extended to deal with the making and breaking of covalent bonds throughout the periodic table. 2) To use the knowledge gained through study of reactive intermediates and reaction mechanisms to make new molecules, new types of bonds, and new materials. The approach we have taken has been to study the reactions of atoms, molecules and ions small enough to be well-characterized by spectroscopic measurements and amenable to theoretical as well as to experimental treatment. We have examined the chemistry of highly reactive short-lived species containing electron-deficient group XIV atoms, including carbenes, carbo-cations CC and CH, silyl radicals RSi., silylenes RSi:, silenes RSi=CR, silicon-centered cations SiH, germylenes, RGe:, germenes RGe=CR, phosphinidenes R-P, and free atoms C, Si, and Ge.
