丰富的质子的极化，而不是低旋磁比的稀核，可以在不到10分钟内使用溶解DNP增强，并转换成一个长寿命的状态离域超过三个耦合质子的合奏。这个过程比异核的超极化和随后的质子磁化转移更直接。
The polarisation of abundant protons, rather than dilute nuclei with low gyromagnetic ratios, can be enhanced in less than 10 min using dissolution DNP and converted into a long-lived state delocalised over an ensemble of three coupled protons. The process is more straightforward than the hyperpolarisation of heteronuclei followed by magnetisation transfer to protons.
