论文摘要
氮NMR光谱具有氮 - 视牙中心的潜力，有可能提供分钟样品的高分辨率光谱。这可能对化学，医学和制药工程具有重要意义。该技术面临的主要障碍之一是，非极化液体样品的扩散拓宽了光谱线，从而限制了分辨率。因此，该领域的实验受到实现样本高极化的努力的阻碍，这是一项艰巨的努力。在这里，我们检查了一个场景，其中液体仅限于少量。我们表明，限制“抵消”扩散的效果，从而克服了NV-NMR光谱仪的解决能力的主要障碍。
Nano-NMR spectroscopy with nitrogen-vacancy centers holds the potential to provide high resolution spectra of minute samples. This is likely to have important implications for chemistry, medicine and pharmaceutical engineering. One of the main hurdles facing the technology is that diffusion of unpolarized liquid samples broadens the spectral lines thus limiting resolution. Experiments in the field are therefore impeded by the efforts involved in achieving high polarization of the sample which is a challenging endeavor. Here we examine a scenario where the liquid is confined to a small volume. We show that the confinement 'counteracts' the effect of diffusion, thus overcoming a major obstacle to the resolving abilities of the NV-NMR spectrometer.
