Structural Correlations of Charge-Transfer Interactions in Aromatic Molecular Clusters

在实验物理化学计划的这个项目中，Michael Topp将使用旋转相干光谱学和其他基于激光的技术来探测含有3-氨酰亚胺和bianthryl的气相团簇的动力学和光谱特性。选择这些体系是因为这些物质在液相中的激发态寿命和荧光光谱显示出强烈的溶剂依赖性。这项研究将确定由电子激发引起的电荷分布变化（包括电荷转移）的相互作用。这些信息对于完全理解凝聚态分子的结构、性质和相互作用是必不可少的。气相簇提供了一个理想的环境来探测溶质和溶剂之间分子相互作用的细节。Topp教授的研究将确定溶剂分子如何影响这些簇中溶质分子的结构和性质。这项研究将增强我们对液相物质的稳定性和反应性的理解，以及对这些性质负责的力

In this project in the Experimental Physical Chemistry Program, Michael Topp will use Rotational Coherence Spectroscopy, and other laser based techniques to probe the dynamical and spectroscopic properties of gas phase clusters containing 3-aminophthalimide and bianthryl. These systems are chosen because of the strong solvent dependence exhibited by the excited state lifetimes and fluorescence spectra of these species in the liquid phase. This research will determine the interactions responsible for changes in the charge distribution, including charge-transfer, induced by electronic excitation. Such information is essential to a complete understanding of the structures, properties, and interactions of molecules in condensed phases. Gas phase clusters provide an ideal environment to probe the details of molecular interactions between solute and solvent. Professor Topp's research will determine how solvent molecules affect the structure and properties of a solute molecule in these clusters. This research will enhance our understanding of the stabilities and reactivities of liquid phase species, and the forces responsible for these properties
