  The NV-NMR spectrometer is a promising candidate for detection of NMR signals
at the nano scale. Field inhomogeneities, however, are a major source of noise
that limits spectral resolution in state of the art NV - NMR experiments and
constitutes a major bottleneck in the development of nano scale NMR. Here we
propose, a route in which this limitation could be circumvented in NV-NMR
spectrometer experiments, by utilising the nanometric scale and the quantumness
of the detector.
