Atomic-scale imaging of a 27-nuclear-spin cluster using a quantum sens
Nuclear magnetic resonance (NMR) is a powerful method for determining the structure of molecules and proteins1. Whereas conventional NMR requires averaging over large ensembles, recent progress with single-spin quantum sensors2–9 has created the prospect of magnetic imaging of individual molecules10–13. As an initial step towards this goal, isolated nuclear spins and spin pairs have been…
