ESR Facility


The Electron Spin Resonance Facility of the Chemistry Department of the University of Basel is addressing research at the interface between inorganic chemistry, organic chemistry, biology, medicine.

We provide the expertise and instrumentation (Brucker ElexSys E 500 at 9.66 GHz, X-band CW EPR spectrometer operating from 2 up to 370K) to characterise paramagnetic centres in a variety of systems:

  1. free radicals formation and decay (by direct ESR and spin trapping) in chemical (radical polymerizations, electrochemistry) and biological reactions (donor/acceptor systems, enzymatic systems, antioxidants influence),
  2. metal centers in small molecular weight complexes and supramolecular systems (polymers, proteins and combination of thereof),
  3. specific regions in polypeptides (dynamics and accessibility of the side chain, local polarity and electrostatic potential), and proteins (prediction of the secondary structure, insertion in various membranes) by spin labeling approach.
