Many chemical reactions involve short-lived and highly reactive intermediates that cannot be observed under ordinary reaction conditions. Hence, much of this chemistry is shrouded in mystery. This project aims to develop the ability to observe and monitor such reactions directly using a combination of spectroscopies at very low temperatures, where the molecules are more stable and reactions slower. These studies will give quantitative information on the nature of the reactive intermediates themselves, the nature of the products formed, and the reaction dynamics, and they are of fundamental importance for an understanding of chemical reactivity generally. The methodology developed will be applicable to the investigation of a wide range of processes.

许多化学反应涉及在普通反应条件下无法观察到的短寿命和高活性中间体。因此，这种化学物质的大部分都笼罩在神秘之中。该项目旨在开发在非常低的温度下直接使用光谱学组合观察和监测此类反应的能力，在这种温度下分子更稳定，反应更慢。这些研究将提供有关反应中间体本身的性质、所形成的产物的性质和反应动力学的定量信息，它们对于理解一般的化学反应性具有根本的重要性。开发的方法将适用于调查范围广泛的过程。
