In this project, funded by the Experimental Physical Chemistry Program of the Chemistry Division, Levis will investigate the behavior of molecules in the presence of intense laser pulses. A long-range goal of these studies is the control of chemical reactions in the gaseous and eventually the solution phase. Special experimental and theoretical tools will be developed towards the realization of these goals. Chemical reactions most often occur along reaction paths that are determined by the intrinsic properties of the reactants. Reactions that lead to desirable reaction products are then not realized unless means are found to control the reactions by means of external intervention. One hopeful method to achieve such control is through modification of the intrinsic molecular properties in the presence of very intense laser fields. The goal of this project is to devise experimental and theoretical techniques that lead to the control of chemical reactions. Students and postdoctoral research associates participate in this research.

在这个由化学部实验物理化学计划资助的项目中，Levis将研究分子在强激光脉冲存在下的行为。这些研究的一个长期目标是控制气体中的化学反应，并最终控制溶液中的化学反应。将为实现这些目标开发特殊的实验和理论工具。化学反应通常发生在由反应物的固有性质决定的反应路径上。因此，除非找到通过外部干预来控制反应的方法，否则不会实现导致所需反应产物的反应。一种有希望实现这种控制的方法是通过在非常强的激光场存在的情况下改变固有的分子性质。这个项目的目标是设计出能够控制化学反应的实验和理论技术。学生和博士后研究助理参与了这项研究。
