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.
实际的纯位移核磁共振实验，尤其是在配备低温探头的仪器上进行时，有时会得到非常令人失望的结果。在此我们首次表明，这是由于样品对流导致信号损失的结果，并展示了对常见纯位移核磁共振实验的一种简单调整，该调整可恢复损失的信号。
