Abstract
We probe nuclear and electron spins in a single molecule even beyond the electromagnetic dipole
selection rules, at readily accessible magnetic fields (few mT) and temperatures (5 K) by resonant radio-
frequency current from a scanning tunneling microscope. We achieve subnanometer spatial resolution
combined with single-spin sensitivity, representing a 10 orders of magnitude improvement compared to
existing magnetic resonance techniques. We demonstrate the successful resonant spectroscopy of the
complete manifold of nuclear and electronic magnetic transitions of up to ΔI(z) = +/- 3 and ΔJ(z) = +/- 12 of
single quantum spins in a single molecule. Our method of resonant radio-frequency scanning tunneling
spectroscopy offers, atom-by-atom, unprecedented analytical power and spin control with an impact on
diverse fields of nanoscience and nanotechnology
