我们通过实验和理论证明，自旋系统和核磁共振探针之间的耦合（负责辐射阻尼）也可以产生多量子相干，即使在通常没有多量子谱的水分子中也是如此。我们讨论了这一观察结果对溶剂抑制序列和制备非平衡自旋态的影响。
We show experimentally and theoretically that coupling between a spin system and the NMR probe, which is responsible for radiation damping, can also act to generate multiple‐quantum coherences, even in molecules such as water which ordinarily have no multiple‐quantum spectrum. We discuss the implications of this observation for solvent suppression sequences and for preparing nonequilibrium spin states.
