Experimental setup

For a free electron    (g= 2.0023), using a field of   0.35 Tesla – 3500 Gauss resonance occurs at a frequency of 9.5 GHz.   ( λ= 3.1 cm). This is in the microwave region, and precisely in the X-band (8-12 GHz) region.

The main parts of an EPR spectrometer are:

  • The microwave source
  • The magnet
  • The cavity
