Jim Weisshaar of the University of Wisconsin at Madison is supported by a grant from the Experimental Physical Chemistry Program to study the reactions of transition metal ions, atoms and ligated species with organic alkanes and alkenes in the gas phase. The studies will be carried out in flow tube and crossed beam apparatuses, with laser induced fluorescence, photoionization mass spectrometry, mass spectrometry and a special emphasis on a new technique of velocity mapping. These studies will be paralleled by ab initio electronic structure calculations. Information on how metal atoms and ions insert into CC and CH bonds will be obtained.Reactions will be studied which involve organometallic species containing transition metal atoms. These reactions have important applications to the catalysis reactions used to breakdown hydrocarbons and synthesize polymers. The new technique of mapping the speed distributions of the products will be used to take "snapshots" of the products as they depart from the reaction. This will enable theoretical models of the reactions to be evaluated.

位于麦迪逊的威斯康星州大学的Jim Weisshaar得到实验物理化学计划的资助，研究过渡金属离子、原子和配位物种与有机烷烃和烯烃在气相中的反应。 研究将在流管和交叉束装置中进行，采用激光诱导荧光、光电离质谱、质谱，并特别强调速度绘图的新技术。 这些研究将通过从头算电子结构计算进行验证。 将获得金属原子和离子如何插入CC和CH键的信息。将研究涉及含有过渡金属原子的有机金属物种的反应。 这些反应在分解烃和合成聚合物的催化反应中有重要的应用。 绘制产物速度分布图的新技术将用于在产物离开反应时拍摄产物的“快照”。 这将使理论模型的反应进行评估。
