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.

该子项目是利用该技术的众多研究子项目之一 资源由 NIH/NCRR 资助的中心拨款提供。子项目和 研究者 (PI) 可能已从 NIH 的另一个来源获得主要资金， 因此可以在其他 CRISP 条目中表示。列出的机构是 对于中心来说，它不一定是研究者的机构。 该研究计划的长期目标是 1) 了解如何扩展有机化学的机理思想来处理整个元素周期表中共价键的形成和断裂。 2）利用通过研究反应中间体和反应机理获得的知识来制造新分子、新型键和新材料。 我们采取的方法是研究足够小的原子、分子和离子的反应，这些反应可以通过光谱测量得到很好的表征，并且可以进行理论和实验处理。 我们研究了含有缺电子第 XIV 族原子的高活性短寿命物质的化学性质，包括卡宾、碳阳离子 CC 和 CH、甲硅烷基 RSi.、亚硅基 RSi:、硅烯 RSi=CR、硅中心阳离子 SiH、甲亚甲基、RGe:、甲锗烯 RGe=CR、膦亚膦 R-P 和自由原子 C， 硅和葛。
