Need your spins sorted? Try pulsed EPR!

INAC researchers recently worked with a Warsaw-based lab to use pulsed electron paramagnetic resonance (EPR) in addition to magnetometry to study the magnetic properties of a sample of doped polyanilines. They were able to sort and identify the individual spin states (non-coupled or coupled by two, three, or four) in the material, rather than simply measuring a sum of the contributions. The data they gathered will be extremely useful in improving the material’s magnetic properties.
This research aims to help chemists and spectroscopists improve spin coupling in the polymer and to develop new magnetic materials made from plant-based polymers.
