Ultrafast Studies of Condensed Phase Chemical Reactivity

这一启动基金奖给加州大学洛杉矶分校，支持本杰明·j·施瓦茨教授的研究。本研究的主题是凝聚态化学反应的超快研究。实验和理论研究都探讨了不同电荷转移到溶剂体系中溶质-溶剂耦合的细节，特别是碱金属阴离子体系。实验利用了最新一代的固态超快激光器，例如，在碘化物系统中，允许直接的单光子激发电荷转移到溶剂带。紫外和红外波段的光谱研究将区分电荷转移到溶剂的各种物理图像。对溶剂、离子和激发条件的进一步研究将使我们对这些反应的动力学有一个基本完整的了解。本研究将通过对溶剂化动力学的实验和理论研究，促进对溶液化学反应性的基本认识。

This starter grant award to the University of California at Los Angeles supports the research of Professor Benjamin J. Schwartz. The theme of the research is ultrafast studies of condensed phase chemical reactivity. Both experimental and theoretical studies explore the details of solute-solvent coupling in different charge-transfer-to-solvent systems, particularly alkali metal anion systems. Experiments take advantage of the newest generation of solid-state ultrafast lasers, allowing direct one-photon excitation of the charge-transfer-to-solvent band in the iodide system, for example. Spectral studies in both the ultraviolet and infrared wavelength regimes will distinguish between the various physical pictures proposed for charge-transfer-to solvent. Additional studies varying the solvent, the ion, and the excitation conditions will provide an essentially complete understanding of the dynamics important in these reactions. This research will advance the fundamental understanding of solution phase chemical reactivity through both experimental and theoretical study of solvation dynamics.
