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.

    Isolation of a Triplet Benzene Dianion

    High-magnetic-field, high-frequency electron paramagnetic resonance demonstrates how coordination chemistry can be leveraged to stabilize a desired electronic/magnetic state in an organic molecule. In this experiment, the long-sought magnetic (triplet) ground state in a benzene ring is stabilized by a pair of metal ions above and below the six-carbon ring.
