This project in the Physical Chemistry Program of the Chemistry Division is a study involving six experiments dealing with various topics in photochemistry and chemical dynamics, each designed to provide new insight. Among the experiments are a three-dimensional sub-Doppler spectroscopy applied to the photodissociation of water; looking at the reaction CN + HCN going to CNH + CN using isotopically labeled reagents; a test of the inversion mechanism in the reaction of H with SiD4 or CD4; Rydberg atom chemistry in the Cs + H2 reaction; looking for spin-aligned products from Hg* + H2; and an intramolecular reaction in 3-fluoropropanol initiated by photodissociation of the OH (or OD) bond to give HF (or DF). %%% One of the goals of a chemist is to elucidate experimentally the elementary mechanisms of a chemical reaction as simply and directly as possible. Chemists are constantly proposing new methods to reach this goal. This project covers six types of elementary chemical reactions which will be investigated by new methods or which will be studied for the first time to illustrate a general principle. The results of such an investigation will allow chemists to gain valuable insights into how chemical reactions occur on the atomic and molecular level.

化学部物理化学课程的这个项目是一项研究，涉及六个实验，涉及光化学和化学动力学的不同主题，每个实验都旨在提供新的见解。在这些实验中，有应用于水的光解的三维亚多普勒光谱；使用同位素标记试剂观察CN+HCN进入CNH+CN的反应；测试H与SiD4或CD4反应的反转机理；Cs+H2反应中的里德堡原子化学；寻找来自Hg*+H2的自旋排列的产物；以及在3-氟丙醇中的分子内反应，通过光解OH(或OD)键得到HF(或DF)。化学家的目标之一是在实验上尽可能简单和直接地阐明化学反应的基本机理。化学家们不断提出新的方法来实现这一目标。这个项目涵盖了六种基本化学反应，它们将用新的方法进行研究，或者将首次进行研究，以阐明一般原理。这样的研究结果将使化学家能够在原子和分子水平上获得关于化学反应如何发生的有价值的见解。
