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，某些自由基的阴离子具有反对化学惯例的电子构型，并且具有出色的自由基稳定性。对这一突破的开发首先需要对这些化合物的内在电子结构进行实验性阐明，以及它与它们的显着特性的关系。该项目将通过修饰仪器来探测自由基阴离子的基本结构和能量，以使多步气离子离子合成有效地与阴离子光学光谱谱图有效耦合。这些研究对于在自由基化学和生物学中揭示了这种现象的范围至关重要，并且可以为未来的聚合催化剂开发。
