Abstract
This brief review highlights the techniques and diverse applications of time-resolved electron paramagnetic resonance(TREPR)spectroscopy,underscoring its essential role in elucidating the structures,spin dynamics,and reactivities of open-shell systems.Furthermore,we discuss the limitations of traditional TREPR methodologies,particularly their challenges in directly observing reactive radical intermediates under real-world reaction conditions.Lastly,we present the latest advancements in TREPR technology developed in our laboratory,specifically ultrawide single-sideband phase-sensitive detection(U-PSD)TREPR,highlighting its significant impact and tremendous potential in advancing free radical chemistry research.We envision promising future applications of TREPR and its pivotal role in enhancing our understanding of mechanisms involved in complex radical processes and photocatalysis.
