Recent work has discovered that certain radical anions have electronic configurations that defy chemical convention and exhibit exceptional radical stability. Exploitation of this breakthrough first requires experimental elucidation of the intrinsic electronic structure of these compounds and how it relates to their remarkable properties. This project will probe the fundamental structure and energetics of radical anions by modifying instrumentation to enable multi-step gas-phase ion synthesis to be efficiently coupled with anion photoelectron spectroscopy. These investigations are essential to revealing the scope of this phenomenon in free radical chemistry and biology and could inform future development of new catalysts for polymerisation.

最近的工作发现，某些自由基阴离子具有违反化学惯例的电子构型，并表现出非凡的自由基稳定性。要利用这一突破，首先需要通过实验阐明这些化合物的内在电子结构及其与其显着性质的关系。这个项目将通过改进仪器来探索自由基阴离子的基本结构和能量学，使多步气相离子合成能够有效地与阴离子光电子能谱耦合。这些研究对于揭示这种现象在自由基化学和生物学中的范围是至关重要的，并可能为未来聚合新催化剂的开发提供信息。
