Electron Spin Resonance (ESR) also known as Electron Magnetic Resonance (EMR) or Electron Paramagnetic Resonance (EPR) is a branch of absorption spectroscopy in which radiations having frequency in the microwave region (0.04 – 25 cm) is absorbed by paramagnetic substances to induce transitions between magnetic energy levels of electrons with unpaired spins. a) Perpendicular and stronger field Required fields are marked *. b) Photodetector Here, we will focus on the spectra of organic and organotransition metal radicals and coordination complexes. b) Both fields should be varying d) Affect the nuclear spin of an atom. a) Field shift Coupling causes the peaks in 1H NMR spectra to be split into, A. two peaks When placed in a magnetic field, all the random spins of the nuclei, A. stop Electron Spin Resonance Spectroscopy or It’s fun to flip electrons! 2.
