The Electron Paramagnetic Resonance Laboratory is able to assist with:

  • Electronic structure of paramagnetic materials
  • Oxidation and spin states of transition metal ions
  • Determination of hyperfine coupling interaction parameters
  • Distance measurements by electron-electron double resonance
  • Spin-lattice (T1) and spin-spin (T2) relaxation times measurements
  • Kinetics of photochemical reactions
