In the last few years, the nitrogen-vacancy defect in diamond has emerged as an exceptional quantum sensor for magnetic and electric fields, capable of detecting proton spins outside the diamond. However, the performance of the NV electron spin alone limits the achievable resolution of an NV NMR spectroscopy experiment to about 200 Hz [2,3]. By using the NV's inherent nitrogen nuclear spin we form a robust hybrid quantum sensor, capable of performing NMR spectroscopy on nanometer sized samples. The hereby obtained spectra are not limited by the electron spin lifetimes, but rather by the sample spins. We perform NMR spectroscopy on spins inside and outside the diamond, reaching a frequency resolution of 10 Hz and 100 Hz, respectively, enough to extract structural information of the molecule.
