STUDIES OF UNUSUAL REACTIVE SPECIES BY ION TRAP AND FTMS

本子项目是利用由NIH/NCRR资助的中心赠款提供的资源的众多研究子项目之一。子项目和研究者（PI）可能已经从另一个NIH来源获得了主要资金，因此可以在其他CRISP条目中表示。列出的机构是中心的，不一定是研究者的机构。本研究计划的长期目标是：1)学习如何将有机化学的机理思想推广到研究元素周期表中共价键的形成和断裂。2)利用通过研究反应中间体和反应机理所获得的知识来制造新分子、新型键和新材料。我们所采取的方法是研究原子、分子和离子的反应，这些反应小到可以用光谱测量来很好地表征，并且可以接受理论和实验处理。我们研究了含有缺电子基团XIV原子的高活性短寿命物质的化学性质，包括碳烯，碳阳离子CC和CH，硅基自由基RSi。硅烯RSi：、硅烯RSi=CR、硅中心阳离子SiH、锗烯RGe：、锗烯RGe=CR、膦烯R-P和自由原子C、Si、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.
