New Approaches in Chemical Dynamics

本项目属于化学学部物理化学项目，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。其中，三维亚多普勒光谱法应用于水的光解；用同位素标记试剂观察CN + HCN生成CNH + CN的反应；H与SiD4或CD4反应的反转机制试验；Cs + H2反应中的Rydberg原子化学从Hg* + H2中寻找自旋排列的产物；3-氟丙醇分子内反应由OH（或OD）键光解生成HF（或DF）引发。化学家的目标之一就是通过实验尽可能简单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达到这一目标。该项目涵盖了六种基本化学反应，这些反应将通过新的方法进行研究，或者将首次研究以说明一般原理。这样的研究结果将使化学家对化学反应是如何在原子和分子水平上发生的有价值的见解。

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.
