Electron Spin Resonance (ESR) describes a suite of techniques forcharacterising electronic systems, with applications in physics, materialsscience, chemistry, and biology. However, the requirement for large electronspin ensembles in conventional ESR techniques limits their spatial resolution.Here we present a method for measuring the ESR spectrum of nanoscale electronicenvironments by measuring the relaxation time ($T_1$) of an optically addressedsingle-spin probe as it is systematically tuned into resonance with the targetelectronic system. As a proof of concept we extract the spectral distributionfor the P1 electronic spin bath in diamond using an ensemble ofnitrogen-vacancy centres, and demonstrate excellent agreement with theoreticalexpectations. As the response of each NV spin in this experiment is dominatedby a single P1 spin at a mean distance of 2.7\,nm, the extension of thisall-optical technique to the single NV case will enable nanoscale ESRspectroscopy of atomic and molecular spin systems.
