Spectroscopy of Main Group Reactive Intermediates

在这项由化学部实验物理化学计划资助的项目中，Clouthier将对主要基团中间体的电子光谱进行研究。这些中间体是以硅、锗和锡原子为基础的，它们的化学结构与基于碳原子的分子有很大不同。有关电子激发态的信息非常稀少，但对这些物种的反应化学非常重要。这些研究的结果将对星际云和星际大气的物理以及CVD制备具有重要工业意义的薄膜具有重要意义。我们对化学气相沉积过程的行为的基本了解还不够深入，这些过程用于制备具有重要工业意义的薄膜，以及星际云和星际大气的分子模拟。虽然以碳原子为基础的分子的化学已被很好地理解，但硅、锗或锡原子取代碳原子的分子却不是这样。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、博士后研究助理和来自其他机构的合作者的协助下进行。学生将获得现代分子光谱学技术方面的经验，为深造或进入科学/技术工作大军做准备。

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.
