Laser Studies of Energy Flow in Polyatomic Molecules

本研究是实验物理化学计划的一部分，旨在研究平动、振动或电子激发的简单原型化学物质与非激发分子之间的气相能量转移。实验将使用高分辨率红外激光技术实现量子态分辨率，以研究具有高平动能的原子和未激发分子之间的能量转移碰撞。将研究电子或高振动激发分子与小气相分子的“溶剂”浴之间的能量流动机制。高能原子和小分子之间的化学反应将被研究，重点是确定最终的振动，旋转和产物物种的平动能。准分子和染料激光器将用于产生这些研究中使用的能量激发态。

This research, part of the Experimental Physical Chemistry Program, is designed to study the gas phase energy transfer between translationally, vibrationally, or electronically excited simple prototypical chemical species and unexcited molecules. Experiments, using high resolution infrared laser techniques enabling quantum state resolution, will be performed to study energy transfer collisions between atoms with high translational energy and unexcited molecules. Energy flow mechanisms between electronically or highly vibrationally excited molecules and a "solvent" bath of small gas phase molecules will be studied. Chemical reactions between high energy atoms and small molecules will be studied with emphasis on the determination of the final vibrational, rotational and translational energies of the product species. Excimer and dye lasers will be used to produce the energetically excited species used in these studies.
