The Role of Water and Other Solvents in Chemical Reactivity

Wilse Robinson教授是由实验物理化学计划资助的，用于研究水和其他溶剂在化学反应中所起的作用。这些研究对于加深我们对溶液中发生的化学反应的分子水平的理解是极其重要的。罗宾逊的研究旨在更好地描述溶剂参与化学反应的超快动力学的分子级结构。这些研究的方法论将把皮秒和飞秒光谱与从超级计算机建模和纯理论获得的直觉结合起来。作为溶剂的水是一个特例，将是许多研究工作的重点。它是一种高度结构化的液体，具有中等强度的定向键。指出在涉及质子、羟基离子和电子的基本离子反应中存在特定的溶剂结构基团。将阐明外来阳离子和阴离子、pH、温度、压力和添加其他溶剂的扰动。

Professor Wilse Robinson is funded by a grant from the Experimental Physical Chemistry Program to study the role which water and other solvents play in chemical reactivity. These studies are extremely important in order to further our molecular level understanding of chemical reactions which take place in solution. Robinson's research is directed toward a better molecular-level structural description of the ultrafast dynamics of solvent participation in chemical reactions. The methodology of these studies will combine picosecond and femtosecond spectroscopies with intuition gained from supercomputer modeling and pure theory. Water as a solvent is a special case, and will be the focus of much of the research effort. It is a highly structured liquid having moderately strong directional bonding. The presence of specific solvent structural moieties in fundamental ionic reactions involving the proton, the hydroxyl ion and the electron is indicated. Perturbations by foreign cations and anions, by pH, temperature, pressure and by the addition of other solvents will be elucidated.
