NMR Spectrometer#

NMR spectrometers measure nuclear resonance in magnetic fields. Their operation is precise but highly environment‑dependent.

Dimensional Core (SET)#

• Spin: primary measurement axis
• Elec: RF detection
• Temp: affects relaxation times

Why Yellow‑Zone#

NMR requires strict field stability and relies on model‑dependent interpretation.

Regime Notes#

• pos‑regime: stable field, homogeneous samples
• Q‑regime: impurities, field drift
• neg‑regime: strong gradients, unstable temperature

Alignment Notes#

Needs explicit field‑stability and sample‑homogeneity notes.
