Assessing the Nature of Chiral-Induced Spin Selectivity by Magnetic Resonance

Understanding chiral-induced spin selectivity (CISS), resulting from chargetransport through helical systems, has recently inspired many experimental and theoreticalefforts but is still the object of intense debate. In order to assess the nature of CISS, wepropose to focus on electron-transfer processes occurring at the single-molecule level. Wedesign simple magnetic resonance experiments, exploiting a qubit as a highly sensitive andcoherent magnetic sensor, to provide clear signatures of the acceptor polarization. Moreover,we show that information could even be obtained from time-resolved electron paramagnetic resonance experiments on a randomly oriented solution of molecules. The proposedexperiments will unveil the role of chiral linkers in electron transfer and could also beexploited for quantum computing applications.
