Spectroscopic Determination of Excited State Properties of Organometallic and Inorganic Compounds

加州大学洛杉矶分校化学系Jeffrey I.Zink博士由化学部无机化学、生物无机化学和金属有机化学项目支持，研究含金属分子的电子激发态。对挥发性有机金属化合物和分子进行了详细的单晶极化电子吸收、发射和共振拉曼光谱测量，这些化合物可能是激光辅助化学气相沉积的前驱物质，这些分子很好地验证了关于激发态耦合和非完全对称模式的理论预测。这些实验的结果将被用来确定处于激发态的金属的几何形状、扭曲、性质和反应。当一种含有金属的化合物吸收光能时，它就会变得“被激发”。在“激发态”下，化合物的许多性质会发生变化，例如，可能会发生通常不会发生的化学反应。本研究将对金属化合物的激发态进行研究，以建立预测和合理化激发态行为的理论方法，并揭示金属化合物分解为有价值的先进材料的途径。

Dr. Jeffrey I. Zink, Chemistry Department, University of California - Los Angeles, is supported by the Inorganic, Bioinorganic, and Organometallic Chemistry Program of the Chemistry Division for an investigation of the electronic excited states of metal-containing molecules. Detailed single crystal polarized electronic absorption, emission, and resonance Raman spectroscopic measurements will be made on volatile organometallic compounds, which could be precursors for laser assisted chemical vapor deposition, and molecules that well test theoretical predictions about excited state couplings and non-totally symmetric modes. The results of these experiments will be used to determine the geometries, distortions, properties, and reactions of the metals in their excited states. When a metal containing compound absorbs light energy, it becomes `excited`. In the `excited state` many of the properties of the compound change and, e.g., chemical reactions can occur that normally do not take place. In this study the excited states of metal compounds will be studied to establish theoretical methods to predict and rationalize excited state behavior, and to uncover the pathways by which metal compounds can be made to decompose into valuable advanced materials.
