本文介绍了一种用于金刚石对顶砧（DAC）核磁共振的单螺线管射频（rf）探头。射频探头提供了一个更高的信噪比（S scinN）比以前的设计，液体样品的DAC-NMR。它诱导了一个几乎均匀的射频场，即使在边缘S scinN也能进行直接测量。它可以在不改变样品压力的情况下安装和拆卸，这提高了实验效率，超过了以前的设计。这种射频探头将有助于核磁共振在极压液体中的应用。
An alternative type of single-solenoid radio frequency (rf) probe for diamond anvil cell (DAC) NMR is described. The rf probe provides a higher signal-to-noise ratio (S∕N) than previous designs for DAC-NMR of liquid samples. It induces a practically homogeneous rf field that enables straightforward measurements even at a marginal S∕N. It can be installed and removed without changing the sample pressure, which enhances the efficiency of experimentation beyond that attainable with previous designs. This rf probe will facilitate the application of NMR to liquids at extreme pressures.
