Available experiments: 

• CW X-band EPR;
• Fourier Transform (FT) EPR and Electron Spin Echo (ESE) techniques – electron spin relaxation times (T1 and T2);
• ESEEM and 2D-HYSCORE – spin density distribution and distances through the hyperfine interaction between electron and nuclear spins;
• SECSY and EXSY – correlations and exchange rates;
• Pulse ENDOR – hyperfine interactions and nuclear spin relaxation;
• Pulse ELDOR – long range distances by electron-electron spin dipolar coupling.
