Abstract: This disclosure relates to determining a spatial configuration of multiple nuclei. An electron dipole generates a spatially varying magnetic field such that each of the multiple nuclei is resonant at a respective resonance frequency defined by the magnetic field at a location of that nucleus. A first signal generator generates a first signal at a first signal frequency such that, as a result of dipole-dipole interaction between the electron dipole and a subset of the multiple nuclei that are resonant at the first signal frequency, a phase of the electron dipole is indicative of a number of nuclei that are resonant at the first signal frequency. A readout module determines the phase of the electron dipole, and determines the spatial configuration of the multiple nuclei based on the phase of the electron dipole. As a result of the high spatial resolution of the sensing the nuclear structure of molecules can be determined with low noise.
