SIFT-Drift Studies of Gas Phase Ion-Molecule Reactions

该奖项由有机动力学计划颁发，支持这项研究 查尔斯·DePuy和Veronica Bierbaum博士的研究 科罗拉多/博尔德。研究的重点将是流动 用馀辉选择离子流管（FA-SIFT）研究气体中的阳离子 相位重点将放在气相反应的甲基阳离子和 几种不同的硼氢化物阳离子与碳氢化合物。反应 将通过同位素标记研究确定途径。FA-SIFT 技术也将用于确定碳-氢键 几个新分子的离解能，并检查 碳负离子在气相中的重排。 这项研究将有助于描述反应离子的内在行为 在气相中，不受溶剂的阻碍。 这些研究是 在大气、等离子体和星际空间中特别重要

This award, made in the Organic Dynamics Program supports the research of Drs. Charles DePuy and Veronica Bierbaum at the University of Colorado/Boulder. The focus of the research will be Flowing Afterglow-Selected Ion Flow Tube (FA-SIFT) studies of cations in the gas phase. Emphasis will be on the gas phase reactions of methyl cations and several different boron hydride cations with hydrocarbons. Reaction pathways will be determined by isotopic labelling studies. The FA-SIFT technique will also be used to determine carbon-hydrogen bond dissociation energies of several new molecules and to examine rearrangements of carbanions in the gas phase. This research will help describe the intrinsic behavior of reactive ions in the gas phase, unencumbered by solvent. Such studies are of particular importance in the atmosphere, plasmas, and interstellar space
