Spectroscopy of Main Group Reactive Intermediates

在这个由化学部实验物理化学计划资助的项目中，Clouthier将对主族中间体的电子光谱进行研究。这些中间体基于Si、Ge和Sn原子，其化学性质与基于碳原子的分子的化学性质显著不同。关于电子激发态的信息是非常稀疏的，但这些物种的反应化学是非常重要的。这些调查的结果将是重要的星际云和拱星大气的物理，以及工业上重要的薄膜CVD制造。我们对化学气相沉积过程的基本理解，用于制造工业上重要的薄膜，以及星际云和星周大气的分子模拟，并没有得到很好的发展。虽然基于碳原子的分子的化学性质是很好理解的，但对于其中硅、锗或锡原子取代碳原子的分子，情况并非如此。这项研究旨在提供有关此类分子性质的信息。这些研究将在学生，博士后研究助理和其他机构的合作者的协助下进行。学生将获得分子光谱学现代技术的经验，为高级研究或进入科学/技术劳动力做准备。

In this project funded by the Experimental Physical Chemistry Program of the Chemistry Division, Clouthier will conduct research on the electronic spectra of main group intermediates. These intermediates are based on Si, Ge, and Sn atoms, whose chemistry is significantly different from that of carbon atom-based molecules. Information about the electronically excited states is very sparse but is of great importance to the reaction chemistry of these species. The results of these investigations will be of importance to the physics of interstellar clouds and circumstellar atmospheres, as well for CVD fabrication of industrially important thin films. Our basic understanding of the behavior of the chemical vapor deposition process for the fabrication of industrially important thin films, as well as for the molecular modeling of interstellar clouds and circumstellar atmospheres is not well developed. While the chemistry of molecules based on the carbon atom is well understood, this is not the case for molecules in which silicon, germanium, or tin atoms take the place of carbon atoms. This research is directed to provide information on the properties of such molecules. The studies will be conducted with the assistance of students, postdoctoral research associates and collaborators from other institutions. Students will gain experience in modern techniques of molecular spectroscopy in preparation for advanced studies or entry into the scientific/technical workforce.
