In this project in the Experimental Physical Chemistry Program of the Chemistry Division, Vaccaro will study the spectroscopy, relaxation, and chemical reactivity of rovibrationally excited polyatomic molecules as a function of both the magnitude and type of excitation of the molecular framework. The first state-to-state measurements of polyatomic reaction dynamics will be performed. Novel multiple-resonance laser techniques will be used to prepare molecules in specific rotation-vibration states. %%% Studies of the reactivity of polyatomic molecules which contain chemically significant quantities of energy of excitation are important because of the information they can reveal about aeronomic and combustion-related processes. On a fundamental scientific level, these transient species can reveal much regarding the nature and origin of such phenomena as mode- or bond-specific chemistry and quantum chaos.

在化学部实验物理化学计划的这个项目中，Vaccaro将研究振动激发的多原子分子的光谱、驰豫和化学反应能力，作为分子框架激发的大小和类型的函数。将进行多原子反应动力学的首次状态对状态测量。新的多共振激光技术将被用来制备处于特定旋转振动状态的分子。%研究多原子分子的反应性是很重要的，因为它们可以揭示有关空气动力学和燃烧相关过程的信息。在基础科学层面上，这些瞬变物种可以揭示许多关于模式或键特定化学和量子混沌等现象的性质和起源。
