From: Pulse sequence design for high field NMR with NV centers in dipolarly coupled samples
(Top) General layout of our protocol containing the RF control over nuclear spins and the MW pulse sequence on the NV ensemble. The magnetic field emitted by the nuclei as a consequence of the RF rotations is depicted in light purple. As time progresses, this field changes its shape, which changes the phase accumulated by the NV, while MW pulses keep always the same structure. (Bottom) Evolution of the expected results for the measurement over the NVs as the experiments progresses, showing a sinusoidal pattern with frequency \(\delta ^*\). In the presence of additional shifts, the measurement outcomes evolve as a sum of sinusoidal components with corresponding frequencies \(\delta ^*_i\), which can be extracted through Fourier transform analysis.
