DNP is cool😎, but electrons are crazy🤪. Understanding electron spin dynamics is important to realize the full potential of DNP.

Dynamic nuclear polarization (DNP) is a technique for increasing the sensitivity of NMR by transferring the polarization from electron spins to nuclear spins. DNP has great potential, but experimental efficiencies are still far below the theoretical optimum, for reasons that are not well understood. In this poster, I will present some case studies showing how EPR can be used to measure electron spin dynamics and decipher the DNP mechanism.
