Electronic Spectroscopy and Dynamics of Cold, Gas Phase Hg- containing Excimers (Chemistry)

在这个项目中，我们将研究一类一般的弱键合汞配合物的结构和动力学。所获得的信息将使此类体系的成键能及其反应路径得以确定。此外，Zwier博士是一名高素质的光谱学家，他将最先进的化学物理研究带入本科大学环境。所要研究的系统在基态时只受范德华力束缚，但在某些激发态下是化学束缚的。用激光诱导荧光光谱研究汞-水、汞-氨、汞-乙烯等汞络合物的转动分辨光谱，以确定基态和激发电子态的结合能和振动频率。弛豫或反应的动力学将通过荧光寿命研究来探索。

In this project, the structure and dynamics of a general class of weakly bonded mercury complexes will be studied. The information obtained will enable the bonding energies of such systems and their reaction paths to be determined. In addition, Dr. Zwier is a highly qualified spectroscopist who is bringing state-of-the- art chemical physics research into the undergraduate college environment. The systems to be studied are bound only by van der Waals forces in the ground state, but are chemically bound in some excited states. The rotationally resolved spectra of such mercury complexes as Hg-water, Hg-ammonia, and Hg-ethylene will be studied by laser-induced fluorescence spectroscopy to determine the binding energies and vibrational frequencies in both the ground and excited electronic states. The dynamics of relaxation or reaction will be probed by fluorescence lifetime studies.
