Gas Phase Ionic Chemistry and Spectroscopy

这项有机动力学计划的拨款支持斯坦福大学约翰·布劳曼教授的继续工作。研究的目的是了解离子和源自中等大小的有机和无机分子的高活性中间体在气相中的结构和反应性之间的关系。本研究将涉及热力学、反应动力学、电子光分离光谱、红外多光子诱导反应和光学光化学。要研究的反应类型包括双分子亲核取代反应、酰基转移反应和质子转移反应。将测定碳氢化合物的酸度、电子亲和力和络合离子（如醇氧化合物/HF加合物）的能量学。这项研究将进一步发展对高活性离子和活性中间体从稳定环境（如溶液或晶体）中移除时的内在化学及其与结构的关系的理解。

This grant in the Organic Dynamics Program supports the continuing work of Professor John I. Brauman at Stanford University. The goal of the research is to understand the relationship between structure and reactivity of ions and highly reactive intermediates derived from moderate-sized organic and inorganic molecules in the gas phase. Thermodynamics, reaction dynamics, electron photodetachment spectroscopy, infrared multiple photon induced reactions, and optical photochemistry will be involved in this study. Reaction types to be studied include bimolecular nucleophilic substitution reactions, acyl transfer reactions, and proton transfer reactions. Acidities of hydrocarbons, electron affinities, and energetics of complex ions such as alkoxide/HF adducts will be determined. This research will further develop an understanding of the intrinsic chemistry, and its relation to structure, of highly reactive ions and reactive intermediates when they are removed from stabilizing environments such as solution or crystals.
