Molecular-Beam Studies of Organic Reactions

点击翻译按钮获取中文摘要

This research, part of the Experimental Physical Chemistry Program, uses seeded nozzle beams to study the dynamics of organic chemi-ionization reactions where the reactants are neutral molecules and the products are ions. This project will provide a qualitative picture of how the reaction proceeds, how bonds are made and broken, and how energy flows from reactants to products. The transfer of a proton from an acid to an organic base to produce an ionized salt will be investigated in a crossed beam apparatus. A second type of reaction involving solvated clusters of molecules will be investigated in the same apparatus. In both cases the experiments consist of measuring the integral reactive cross section as a function of the initial energy. The angular and energy distributions of the products will also be determined.
