Aqueous Solvation Energetics and the Accommodation of Chargein Water Clusters Using Merged Beam Recombination of Cluster Ions

在这个由化学系资助的实验物理化学项目中，科教授(俄亥俄州立大学)将建造一种新的装置，在其中，一束带正电荷的溶剂化离子束与一束类似的负电荷离子束轻轻地合并。重组将通过检测快速移动的中性产物来监测。这将允许产生溶剂分离的离子对团簇，并将导致阐明强电解质的逐级溶剂化能。带电物种在溶液中的%-%反应位于许多化学反应的核心，但关于介入性溶剂在影响反应过程中的详细作用，几乎没有确切的信息可用。Coe教授(俄亥俄州立大学)将通过建立一种装置来解决这个问题，该装置将首次确定反应物种周围必须有多少溶剂分子，以防止正电荷物质立即与负电荷物种反应。这将有助于回答更普遍的问题，即需要多少分子来定义化学家所说的一种物质在另一种物质中的溶液是什么意思。

In this Experimental Physical Chemistry project funded by the Division of Chemistry, Prof. Coe (Ohio State University) will build a novel apparatus in which a molecular beam of positively charged, solvated ions is gently merged with a similar beam of negatively charged ions. Recombination will be monitored by detecting fast moving neutral products. This will permit production of solvent-separated ion pair clusters, and will lead to elucidation of step-wise solvation energies of strong electrolytes.%%% Reactions of charged species in solution lie at the heart of many chemical reactions, but very little hard information has been available about the detailed role of intervening solvent in influencing the course of the reaction. Prof. Coe (Ohio State University) will address this question by building an apparatus which will make it possible for the first time to determine how many solvent molecules there must be around the reacting species in order to keep positively charged materials from reacting immediately with negatively charged species. This will help to answer the more general question of how many molecules are needed to define what chemists mean by a solution of one substance in another.
