The Experimental Physical Chemistry program supports the collaborative research projects of Professor Leah O'Brien at Southern Illinois University and Professor James O'Brien at the University of Missouri, St. Louis. The O'Briens and their students will use high-resolution electronic spectroscopy to study platinum- and palladium-containing radicals in the gas phase. Absorption spectra will be obtained using an intracavity laser spectrometer located at the University of Missouri, St. Louis. Visible and near-infrared emission spectra will be recorded using the Fourier transform emission spectrometer at the Kitt Peak McMath-Pierce Solar Observatory. These high-resolution spectroscopic studies will be complemented by theoretical calculations to understand the details of the electronic structure and bonding in the transition metal systems. These species are characterized by open shell structures, which give rise to a host of interactions between nuclear, electronic, vibrational, and rotational degrees of freedom. The work will lead to a deeper understanding of metal-ligand interactions and potentially provide insight on metal-catalyzed reactions. This collaborative project between researchers at a primarily undergraduate institution and a major research university will train undergraduate and MS level graduate students in the techniques of contemporary experimental and theoretical spectroscopy. The project also contains an outreach program that will allow talented high school students to participate in the research.

实验物理化学计划支持南伊利诺伊大学的Leah奥布莱恩教授和圣路易斯密苏里州大学的James奥布莱恩教授的合作研究项目。 奥布莱恩夫妇和他们的学生将使用高分辨率电子光谱学来研究气相中含铂和钯的自由基。 将使用位于圣路易斯密苏里州大学的腔内激光光谱仪获得吸收光谱。 可见光和近红外发射光谱将使用基特峰麦克马思-皮尔斯太阳观测站的傅里叶变换发射光谱仪记录。这些高分辨率光谱研究将通过理论计算来补充，以了解过渡金属系统中电子结构和键合的细节。 这些物种的特征是开放的壳层结构，这引起了核，电子，振动和旋转自由度之间的相互作用的主机。 这项工作将导致对金属-配体相互作用的更深入理解，并可能提供对金属催化反应的见解。这个主要是本科院校和主要研究型大学的研究人员之间的合作项目将在当代实验和理论光谱学技术方面培训本科生和硕士研究生。该项目还包括一个外展计划，将允许有才华的高中生参与研究。
