a Pulse sequence for performing nuclear spin Rabi experiments (M = N = 100). Raw b and processed data c from the PROPI measurement. In c Rabi oscillations are observed, which frequency decreases with decreasing RF amplitude (input at the RF amplifier) (upper to lower graph). Red lines correspond to cosine fits. A Rabi frequency of (19.1 ± 0.5)kHz (upper plot) and (9.5 ± 0.5)kHz (lower plot) is estimated
