The Experimental Physical Chemistry Program supports Dr. Zwier to investigate the structure and dynamics of a general class of weakly bonded mercury complexes. The information obtained will enable the bonding energies of such systems and their reaction paths to be determined. The systems being investigated 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 are being studied by laser-induced fluorescence spectroscopy to determine the binding energies and vibrational frequencies in both the ground and excited states. The dynamics of relaxation and reaction are being probed by fluorescence lifetime studies.

实验物理化学计划支持Zwier博士研究一般类型的弱结合汞络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。所研究的系统在基态时只受范德华力约束，但在某些激发态下受化学约束。用激光诱导荧光光谱研究了汞-水、汞-氨、汞-乙烯等汞配合物的转动分辨光谱，以确定其基态和激发态的结合能和振动频率。通过荧光寿命研究探索了弛豫和反应的动力学。
