C-C and C-H Bond Activation by Transition Metal Cations: Vibrational and Electronic Spectroscopy and Dynamics of Reactants, Products and Intermediates

在这个由化学部门实验物理化学项目资助的项目中，Metz将对C-C和C-H键被激活的过渡金属阳离子的反应物、产物和中间体进行光谱和动力学研究。红外（IR）光谱学将用于扩展先前对电子状态的研究，也包括离子的振动基态。红外吸收监测通过光解分子标记与弱结合旁观者分子或光解未标记分子。具体来说，要研究的系统包括参与甲烷转化为甲醇、甲烷转化为较大碳氢化合物和较大碳氢化合物活化的离子。也要研究大气和天文兴趣的小离子。这项研究将与学生和博士后研究助理一起完成。

In this project, funded by the Experimental Physical Chemistry Program of the Chemistry Division, Metz will pursue spectroscopic and dynamical studies of reactants, products, and intermediates of transition metal cations in which the C-C and C-H bonds are activated. Infrared (IR) spectroscopy will be used to extend previous studies of electronic states to also include the vibrational ground states of the ions. IR absorption is monitored via photodissociation of molecules tagged with a weakly bound spectator molecule or by photodissociation of untagged molecules. Specifically, systems to be studied include ions involved in the conversion of methane to methanol, conversion of methane to larger hydrocarbons, and activation of larger hydrocarbons. Also to be studied are small ions of atmospheric and astronomical interest. This research will be done with students and postdoctoral research associates.
