The facility is located in room 29 of the Chemistry-Physics Building. ܒ� Since the magnetic field interacts with the spin, the spin of the system has to be nonzero. 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. Figure 1.1. Here, we will focus on the spectra of organic and organotransition metal radicals and coordination complexes. (I 0, always multiples of .) ELECTRON PARAMAGNETIC RESONANCE SPECTROSCOPY (EPR) LECTURE NOTES: DR. CYRIAC MATHEW Lecture notes: Dr. Cyriac Mathew EPR spectroscopy is applicable to species (atoms, molecules or ions) containing one or more electrons with unpaired spins, and is observed in the microwave region of electromagnetic radiation.

The magnetic dipole moment of this unpaired electron, µ B, is thus equal to µ The facility currently comprizes an X-band Bruker EMX300 instrument with a cryostat and temperature controller for routine use at temperatures as low as 80 K. The ESR is frequently called as electron paramagnetic resonance spectroscopy and electron magnetic resonance spectroscopy. Electron Paramagnetic Resonance spectroscopy, or EPR, ESR (electron spin resonance) or FMR (ferromagnetic resonance) is a method for directly observing unpaired electrons.
