- In field B apply RF field to material at Larmor frequency ω_0
- Coil of L_0 perpendicular to B_0 to induce spin flip
- LCR circuit (so that ω_0=1/√LC ) to observe change in impedance with frequency
- As frequency changes: circuit response to Q-curve and polarization signal
- Sweep frequency around ω_0 to integrate in ω.
