液态超极化方法的进展使高分辨率NMR光谱学的新应用成为可能。利用来自超极化的强信号增强允许在低浓度下或以高时间分辨率执行NMR光谱。利用高的,但迅速衰减的超极化在液体状态下需要新的技术接口超极化设备与液体状态NMR光谱仪。本文重点介绍了快速进样,高分辨率NMR光谱与超极化技术产生的溶解动态核极化(D-DNP)和仲氢诱导极化(PHIP)。这些方法很受欢迎,尽管不是唯一的方法来产生液体样品的高偏振水平。气体和液体驱动进样技术与这两种超极化方法兼容。快速进样技术与单次或少量扫描的适应性NMR实验相结合。它们将液态超极化的应用扩展到具有极短弛豫时间的自旋,提供对样品条件的增强控制,并允许混合实验以真实的时间研究反应。
Advances in liquid state hyperpolarization methods have enabled new applications of high-resolution NMR spectroscopy. Utilizing strong signal enhancements from hyperpolarization allows performing NMR spectroscopy at low concentration, or with high time resolution. Making use of the high, but rapidly decaying hyperpolarization in the liquid state requires new techniques to interface hyperpolarization equipment with liquid state NMR spectrometers. This article highlights rapid injection, high resolution NMR spectroscopy with hyperpolarization produced by the techniques of dissolution dynamic nuclear polarization (D-DNP) and para-hydrogen induced polarization (PHIP). These are popular, albeit not the only methods to produce high polarization levels for liquid samples. Gas and liquid driven sample injection techniques are compatible with both of these hyperpolarization methods. The rapid sample injection techniques are combined with adapted NMR experiments working in a single, or small number of scans. They expand the application of liquid state hyperpolarization to spins with comparably short relaxation times, provide enhanced control over sample conditions, and allow for mixing experiments to study reactions in real time.
