Ringed atoms belong to a group on the selected nucleus; hover one to see its shift, or hover a peak in the spectrum to light up its atoms.
The free induction decay: the sum of every line's oscillation, decaying with T₂*. Its Fourier transform is the spectrum.
Wheel to zoom at the cursor, drag to pan, double-click to fit. Click a peak for its lines. High ppm is on the left, as on every spectrometer.

Inversion recovery maps T₁, a CPMG train maps T₂; with any other sequence the panel shows the sample's relaxation curves and the T₂* that the shim quality produces.
