Experimental probes of the singlet-triplet gap, photophysics and photochemistry of simple carbenes

在这个由化学系实验物理化学计划资助的项目中，马奎特大学的Reid教授将通过线性和非线性光谱技术对卡宾的光谱、光物理和光化学性质进行各种研究。 这项工作包括两个部分，将集中在这些系统的最低电子态之间的单重态-三重态间隙。 第一部分将致力于一系列具有单重电子基态和可变单重-三重态间隙的卤代卡宾的自旋-轨道间隙和自旋-轨道介导的相互作用的表征。 第二部分研究卤代卡宾的光物理和光化学。 由于卡宾的反应性质，对这些性质的理解进展受到实验挑战的阻碍。简单卤代卡宾在地球高层大气的化学中起着重要的作用，这项工作将大大有助于提高我们对这些反应系统的理解。 这项研究将与研究生和本科生谁将获得当代物理化学的宝贵培训进行。

In this project, funded by the Experimental Physical Chemistry Program of the Chemistry Division, Prof. Reid of Marquette University will conduct a variety of investigations on the spectroscopic, photophysical and photochemical properties of carbenes by means of linear and nonlinear spectroscopic techniques. The work consists of two parts and will focus on the singlet-triplet gap between the lowest electronic states of these systems. The first part will be devoted to the characterization of the spin-orbit gap and spin-orbit mediated interactions in a series of halocarbenes with a singlet electronic ground state and variable singlet-triplet gaps. The photophysical and photochemistry of the halocarbenes will be studied in the second part. Progress in the understanding of these properties has been impeded by experimental challenges owing to the reactive properties of the carbenes. Simple halocarbenes play an important role in the chemistry of the earth's upper atmosphere and this work will go a long way toward the improvement of our understanding of these reactive systems. This research will be conducted with graduate and undergraduate students who will acquire valuable training in contemporary physical chemistry.
