In this project in Experimental Physical Chemistry, Chemistry Division, Felker will use rotational coherence spectroscopy to obtain geometric structures of large species in supersonic molecular beams. This includes studies of aromatic-aromatic dimers and higher clusters, and investigations of how hydrogen-bonded networks evolve with cluster size. %%% By exposing molecules in the gas phase to short, sharp pulses of laser light at the proper frequency, Prof. Felker (UCLA) will obtain information about geometric structures of a small, controlled number of interacting molecules. This information is very useful for understanding how molecules behave in the initial stages of a wide variety of chemical reactions.

在化学学部实验物理化学的这个项目中，Felker将使用旋转相干光谱学来获得超音速分子束中大物种的几何结构。这包括芳香-芳香二聚体和更高簇的研究，以及氢键网络如何随着簇大小而演变的研究。通过将气相分子暴露在适当频率的短而尖锐的激光脉冲中，Felker教授（UCLA）将获得有关少量、受控数量的相互作用分子的几何结构的信息。这一信息对于理解分子在各种化学反应初始阶段的行为是非常有用的。
