摘要

定向TOCSY脉冲序列元件将相干性主要转移到“正向”反相相干中,同时抑制同相和“反向”反相相干。这种基于目标相干“方向”的选择原理为拥挤谱的简化提供了一种新的方法。在这篇文章中,有向TOCSY理论提出了线性自旋系统,经常发现在碳标记的生物分子。

Directed TOCSY, a Method for Selection of Directed Correlations by Optimal Combinations of Isotropic and Longitudinal Mixing

The directed TOCSY pulse sequence element transfers coherence predominantly into “forward-directed” antiphase coherences while simultaneously suppressing in-phase and “backward-directed” antiphase coherences. This novel selection principle, based on the “direction” of the target coherences, provides a new approach for the simplification of crowded spectra. In this article, the theory of directed TOCSY is presented for linear spin systems that are frequently found in carbon-labeled biomolecules.
