Electron Magnetic Resonance Facility (EMR)

EMR stands for Electron Magnetic Resonance, which covers a variety of magnetic resonance techniques associated with the electron. The most popular of those techniques is Electron Paramagnetic/Spin Resonance (EPR/ESR). In simplified terms, EPR/ESR can be performed on any sample that has unpaired electron spins.

EPR/ESR has proven an indispensable tool in a large range of applications in physics, materials science, chemistry and biology, including studies of impurity states, molecular clusters, antiferromagnetic, ferromagnetic and thin film compounds, natural or induced radicals, optically excited paramagnetic states, electron spin-based quantum information devices, transition-metal based catalysts; and for structural and dynamical studies of metallo-proteins, spin-labeled proteins and other complex bio-molecules and their synthetic models.
