ESR Spectrometer

 
Description
   JEOL Model JES FA200 instrument is the state of the art Electron Spin Resonance (ESR) spectrometer used for the measurement
        of species that contain unpaired electrons (Free radicals, transition metal complexes, odd-electron molecules, rare earth ions etc.)
