EPR spectroscopy is a technique for studying paramagnetic systems. Its principle is based on the interaction of a magnetic field with the electronic spins present within the sample, which gives access to these magnetic properties.

The EPR platform hosted by LASIRE is equipped with three EPR spectrometers, two pulsed (X and Q) and an imager integrated into the INFRANALYTICS infrastructure. EPR measurements in continuous and pulsed mode are carried out within the platform on a variety of materials used in different research fields such as catalysis, energy storage and more particularly on biological systems
