Spectroscopic Investigations with Global Modeling of Hypersurfaces and Related Dynamics in Neutral Hydrogen Bond Dimers

在化学系实验物理化学项目中，德克萨斯A&M大学的Bevan教授和Lucchese教授将使用脉冲激光来表征气相系统的氢键动力学。通过利用应用于相对简单的双原子和三原子系统的现代高分辨率光谱技术，将有可能在不适用于更复杂情况的细节水平上测试基本氢键性质的定量模型。%氢键是分子间最重要的相互作用之一。这种相互作用会影响水的沸点和冰点以及遗传物质(DNA)的结构等各种性质。在简单的气相体系中可以很好地研究快速氢键形成的时间过程，这些气相体系可以进行详细的理论计算。Bevan和Lucchese教授将为这类系统进行实验并开发合适的理论，结果将是对无处不在的氢键过程有更深的理解。

In this project in the Experimental Physical Chemistry program of the Chemistry Division, Professors Bevan and Lucchese of Texas A&M University will use pulsed lasers to characterize hydrogen bond dynamics of gas phase systems. By making use of modern high resolution spectroscopic techniques applied to relatively simple diatomic and triatomic systems, it will be possible to test quantitative models for fundamental hydrogen bond properties at a level of detail not suitable for more complex situations. %%% Hydrogen bonding is one of the most significant interactions between molecules. This kind of interaction influences such diverse properties as the boiling and freezing points of water and the structure of genetic material (DNA). The time course of rapid hydrogen bond formation can best be investigated in simple gas phase systems which are amenable to detailed theoretical calculations. Professors Bevan and Lucchese will conduct experiments and develop appropriate theory for such systems, and the result will be a deeper understanding of the ubiquitous hydrogen bonding process.
