Spectroscopy and Dynamics of Open-Shell van der Waals Molecules

在化学系实验物理化学计划的这个项目中，海文教授将研究开壳范德华分子的电子光谱。这样的研究应该有助于理解包含未配对电子的原子或分子的碰撞过程。由双原子自由基和惰性气体原子组成的几个原型分子的高分辨率电子光谱将被获得。由这些光谱得到的分子常数将被用来确定电子激发态和基态的势能面。将测量激发态的电子和振动预解离速率，并基于实验得出的势能面计算这些速率。

In this project in the Experimental Physical Chemistry Program of the Chemistry Division, Prof. Heaven will study the electronic spectra of open-shell van der Waals molecules. Such studies should help understand collisional processes involving atoms or molecules having unpaired electrons. High resolution electronic spectra will be obtained for several prototype molecules consisting of diatomic radicals and a noble gas atom such as neon or argon. Molecular constants derived from these spectra will be used to determine potential energy surfaces for the electronically excited and ground states. Electronic and vibrational predissociation rates will be measured for excited states, and calculations of these rates will be made based on experimentally derived potential energy surfaces.
