Abstract
We shall overcome: As a result of efforts to overcome the sensitivity challenge of liquid-state NMR spectroscopy, a thousand-fold signal enhancement was achieved by dynamic nuclear polarization (DNP) for C signals at high magnetic field (3.4 T) and room temperature, thereby exceeding the predicted limitations of high-field liquid-state in situ DNP.

我们终将克服困难
通过克服液相 NMR 光谱灵敏度挑战的努力，在高磁场（3.4T）和室温下实现了 C 信号的动态核极化（DNP）的千倍信号增强，从而超过了高场液相原位 DNP 的预测限制。
