Nuclear magnetic resonance (NMR) spectroscopy plays a central role in modern science, with applications ranging from fundamental physics and chemistry to biomedical imaging. NMR spectroscopy can provide detailed information about the structure and dynamics of molecules, but the realization of measurements with sensitivities at the single-molecule level requires fundamentally new detection strategies. Nitrogen-Vacancy (NV) color centers in diamond have emerged as unique magnetic resonance sensors, marked by the recent remarkable demonstrations of nanoscale spectroscopy and imaging of single electron and nuclear spins. Our goal is to extend the magnetic resonance techniques using NV-centers to Zero- and Ultralow-Field NMR (ZULF-NMR), an alternative technique where measurements are performed in the absence of a strong external magnetic field, which is already used to investigate macroscopic NMR samples. ZULF-NMR allows us to perform single-molecule identification via analysis of J-coupling data.We report on our current efforts in designing, constructing and characterizing a single-NV-based ZULF-NMR spectrometer in Mainz.
