a, Molecular rotational and hyperfine spectrum measured at 60 G. Green, blue and orange lines are the theoretical predictions using molecular parameters in refs. 54,56 for microwave transitions from \(\left|\uparrow \right\rangle \) to selected hyperfine states in the N = 1 manifold using π, σ−, and σ+ polarization, respectively. The transition on the far right, indicated by the black arrow, is the \(\left|\uparrow \right\rangle \) to \(\left|\downarrow \right\rangle \) transition. b, Sample Rabi oscillation between \(\left|\uparrow \right\rangle \) and \(\left|\downarrow \right\rangle \). The extracted Rabi frequency from this measurement is 2π × 9.529(4) kHz. Error bars are s.e.m.
