实际的纯频移核磁共振实验，特别是在配备了低温探头的仪器上，有时会得出非常令人失望的结果。在这里，我们首次证明这是样品对流造成的信号损失的结果，并演示了对常见的纯位移核磁共振实验的简单调整，以恢复丢失的信号。
Practical pure shift NMR experiments, especially on instruments equipped with cryoprobes, can sometimes give very disappointing results. Here we show for the first time that this is a consequence of signal loss due to sample convection, and demonstrate a simple adjustment to common pure shift NMR experiments that restores the lost signal.
