Dissociation Dynamics of Reactive Intermediates

在化学部实验物理化学计划的这个项目中，Continetti将使用负离子光解离装置研究小分子气相自由基的离解动力学。Continetti将把负离子光剥离和中性碎片平移能谱结合起来。感兴趣的体系包括HO2、CH3O2、C2O和CH2CHO。这些结果将为深入了解这些物种的离解状态、分解途径和键离解能的性质提供依据。这个研究项目将研究一些不稳定和瞬时的分子的分子结构和电子组成，这些分子很难用其他技术来研究。从这项研究中获得的信息的可能应用包括燃烧化学、大气反应、化学气相沉积和超临界水反应堆。

In this project in the Experimental Physical Chemistry Program of the Chemistry Division, Continetti will study the dissociation dynamics of small gas-phase radicals using a negative ion photodetachment apparatus. Continetti will combine negative-ion photodetachment with neutral-fragment translational energy spectroscopy. Systems of interest include HO2, CH3O2, C2O, and CH2CHO. The results will provide insights into the nature of dissociative states, decomposition pathways, and bond dissociation energies of these species. %%% This research project will examine the molecular structure and electronic composition of a number of unstable and transient molecules which are difficult to study by other techniques. Possible applications of information obtained from this research include combustion chemistry, atmospheric reactions, chemical vapor deposition, and supercritical water reactors.
