Studies of Cluster and Transient Molecule Dynamics by Dissociative Photodetachment

在这个由化学部实验物理化学计划和多学科活动办公室提供的仪器资金支持的项目中，Continetti将使用他实验室开发的中性解离动力学技术继续研究气相中瞬时分子和分子簇的解离动力学，中性解离动力学是负离子光分离和中性碎片平移能谱的组合。要研究的问题包括臭氧解离中的同位素效应，燃烧和大气过程中感兴趣的瞬时分子，以及二聚体阴离子的光化学。这项研究项目将研究一些不稳定和瞬时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 supported by the Experimental Physical Chemistry Program of the Chemistry Division with funds for instrumentation provided by the Office of Multidisciplinary Activities, Continetti will continue studying the dissociation dynamics of transient molecules and molecular clusters in the gas phase using a technique developed in his laboratory, neutral dissociation dynamics, which is a combination of negative-ion photodetachment and neutral-fragment translational energy spectroscopy. Issues to be examined include isotope effects in the dissociation of O3, transient molecules of interest in combustion and atmospheric processes, and the photochemistry of dimer anions. 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.
