Electron Paramagnetic Resonance Spectroscopy
Electron paramagnetic Spectroscopy, or EPR for short, is used study molecules and reactions that involve a species with an unpaired electron. Traditional NMR techniques yield little to no useful information on paramagnetic species due to the greatly accelerated relaxation rate of the NMR signal.
In 2011 the department acquired a Bruker EMXPlus EPR. This EPR is equipped with a helium recycling unit which allows for the acquisition of low temperature EPR spectra without the need to constantly add liquid helium. The helium recycler significantly reduces the cost of operation for low temperature experiments.
