动态核极化（DNP）可以提高核磁共振（NMR）的灵敏度，但在高磁场下的液态下具有挑战性。在这项研究中，我们证明了显着的增强NMR信号（高达70 C-13）在液体状态下的标量Overhauser DNP在14.1 T，高分辨率（类似于0.1 ppm）和相对较大的样品体积（类似于100 μ L）。
Dynamic Nuclear Polarization (DNP) can increase the sensitivity of Nuclear Magnetic Resonance (NMR), but it is challenging in the liquid state at high magnetic fields. In this study we demonstrate significant enhancements of NMR signals (up to 70 on C-13) in the liquid state by scalar Overhauser DNP at 14.1 T, with high resolution (similar to 0.1 ppm) and relatively large sample volume (similar to 100 mu L).
