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.

Jeffrey I. Zink博士，加州大学洛杉矶分校化学系，受到化学系无机、生物无机和有机金属化学项目的支持，对含金属分子的电子激发态进行了研究。将对挥发性有机金属化合物进行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体，也可以很好地测试激发态耦合和非完全对称模式的理论预测。这些实验的结果将用于确定金属在激发态下的几何形状、变形、性质和反应。当含金属的化合物吸收光能时，它就会被“激发”。在“激发态”下，化合物的许多性质发生了变化，例如，可以发生通常不发生的化学反应。本研究将研究金属化合物的激发态，建立理论方法来预测和合理化激发态行为，并揭示金属化合物分解成有价值的先进材料的途径。
