This workshop will embark on a comprehensive journey through the fascinating world of Electron Paramagnetic Resonance (EPR) spectroscopy. The workshop covers various topics of EPR from basic theory to advanced topics where learners will explore the fundamental principles that govern the interaction of unpaired electrons with magnetic fields. Further, learners will understand the meaning of the hyperfine interaction and how the EPR can be used as a powerful spectroscopic tool in characterizing organic molecules, protein structure and function, the crucial electron transfer processes in both biological and bio-mimicking systems from outstanding researchers in the field. This workshop will help researchers how to interpret EPR data for meaningful research outcomes, thus preparing them for more advanced applications in research and industry.
