a, c Variations in the molecular state probabilities a as \(\Delta B\) is scanned from \({-}\,5\) meV to \({+}\,5\) meV and c as \(\Delta B\) is scanned from \(+\,5\) meV to \({-}\,5\) meV. b Zeeman diagram for these spin states as \(\Delta B\) changes from \({-}\) 5 meV to \({+}\) 5 meV. d Variations in the molecular state probabilities as functions of the bias voltage when the molecule’s spin state is initially prepared such that \(P_{|0,+S\rangle }=1\) and \(P_{i}=0\)
