Studies of Cluster and Transient Molecule Dynamics by Dissociative Photodetachment

在这个由化学部实验物理化学项目和多学科活动办公室提供的仪器资助的项目中，Continetti将继续研究瞬态分子和分子团在气相中的解离动力学，使用他实验室开发的技术，中性解离动力学。这是一种结合负离子光剥离和中性碎片平动能谱的方法。要研究的问题包括O3解离中的同位素效应，燃烧和大气过程中感兴趣的瞬态分子，以及二聚阴离子的光化学。该研究项目将研究一些其他技术难以研究的不稳定和瞬态分子的分子结构和电子组成。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.
