The nitrogen vacancy (NV) centre in diamond has proven to be an outstanding magnetic field sensor by enabling nanoscale NMR to be performed at ambient conditions. Recently, a few experiments have demonstrated that the sensitivity of the NV center is sufficient to perform NMR spectroscopy at the single molecule level. However, the spectral resolution of the NV center is lacking, and to date has not allowed structural information on external molecules to be obtained. Here we discuss work on improving the resolution of the NV center, to a level enabling detection of chemical shifts. This would allow for non-destructive structural analysis of single molecules and bring NV-based NMR spectroscopy closer to atomic level imaging.
