This presentation delves into Electron Paramagnetic Resonance (EPR) and Electron Spin Resonance (ESR), exploring key concepts such as the Landé factor (gS), the interaction of electron spins in a magnetic field (B0), and the significance of phase-sensitive detection. The signal obtained during EPR spectroscopy is the first derivative of absorption intensity, illustrated through examples such as the CH3.H2COCH3 EPR spectrum of the benzene radical anion. Visual aids and templates provide clarity on ΔE = gB0h/2π, enhancing understanding for students and researchers alike.
