With this grant from the Organic Dynamics Program, Professor Thomas H. Morton of the University of California, Riverside, will examine the gas phase chemistry of organic cations which react via ion-dipole complexes. The neutral products from the reactions of organic cations generated by 70eV electron impact will be examined by using an electron bombardment flow reactor. This reactor will provide stereochemical information about cation rearrangements which will be critical in order to understand ion molecule reactions. Gaseous cations generated by resonance enhanced multiphoton ionization will also be examined. Ionizations of specific conformations of molecules will be studied by slowing down conformational changes through rapid cooling by supersonic jet expansion. %%% The chemistry of gas phase molecules from which an electron has removed will be examined. The neutral products from these reactions will be isolated and identified. Several molecules which can exist in more than one rapidly interconverting geometry will also be examined. These molecules will be cooled to stop their interconversions and the chemistry of each geometric form of the molecule will be examined.

在有机动力学项目的资助下，加州大学河滨分校的托马斯·H·莫顿教授将研究通过离子-偶极络合物反应的有机阳离子的气相化学。由70 eV电子轰击产生的有机阳离子反应产生的中性产物将用电子轰击流动反应堆进行检测。该反应器将提供有关阳离子重排的立体化学信息，这对了解离子分子反应至关重要。还将研究由共振增强多光子电离产生的气态阳离子。将通过超音速喷射膨胀的快速冷却来减缓构象变化，从而研究特定分子构象的电离。%将考察电子被移走的气相分子的化学。这些反应的中性产物将被分离和鉴定。几个分子可以存在于一个以上的快速相互转换的几何图形中，也将被研究。这些分子将被冷却，以停止它们的相互转化，并将检查分子的每种几何形状的化学。
