Abstract
A new family of NMR pulse sequences is reported for the recording of para-hydrogen enhanced NMR spectra. This Only Para-hydrogen SpectroscopY (OPSY) approach uses coherence selection to separate hyperpolarized signals from those of fully relaxed and thermally equilibrated protons. Sequence design, performance, practical aspects and applicability to other hyperpolarization techniques are discussed.
摘要
一种新的 NMR 脉冲序列家族被报道用于记录顺磁氢增强 NMR 谱。这种仅顺磁氢谱（OPSY）方法使用相干选择将超极化信号与完全弛豫和热平衡质子的信号分离。讨论了序列设计、性能、实际方面以及对其他超极化技术的适用性。
