The Theoretical and Computational Chemistry Program in the Chemistry Division is supporting a project at Clarkson University under the supervision of Dr. Larry Eno on the theoretical study of laser-induced transitions between electronic surfaces in reactive molecular collisions. The extent to which the laser field can be used as a probe of the dynamics of a collinear reaction is being studied with regard to variation in the laser intensity, field frequency, polarization, collision energy, internal energy, and other factors. Complications such as rotating wave breakdown and multi-electronic surface effects are being considered. %%% A major current problem in chemical physics is to obtain greater understanding of what actually happens during the course of a chemical reaction, i.e., during the short time in which reacting molecules approach each other, pass through an intermediate transition stage, and separate as products. This project is a theoretical investigation to determine how laser probes can be used to provide information during this brief period.

在拉里·埃诺（Larry Eno）博士的监督下，化学部的理论和计算化学计划在反应性分子碰撞中的激光诱导的电子表面之间的过渡方面支持克拉克森大学的一个项目。 在激光强度，场频率，极化，碰撞，内部能量和其他因素的变化方面，研究了激光场用作共线反应动力学的探针的程度。正在考虑诸如旋转波击穿和多电子表面效应之类的并发症。 %% %%化学物理学的主要当前问题是对化学反应过程中实际发生的事情有更多的了解，即在短时间内反应分子相互接近，穿过中间过渡阶段，并将其分开为产物。 该项目是一项理论研究，旨在确定如何在此简短期间使用激光探针来提供信息。
