FIG. 8.

(Color online) Measured even-order multiple spin correlations in adamantane as a function of time T in Fig. 2. The shapes represent the FID (▪) and echoes at various τ: τ = 100 µs (⋆), τ = 150 µs (▴), and τ = 200 µs (▾). The colors are: zeroth order correlations (black), second order correlations (red), fourth order correlations (blue), sixth order correlations (green), eighth order correlations (orange), tenth order correlations (purple), and twelfth order correlations (gray). The signal intensities have been renormalized to emphasize the common long-time decays after ~ 200 µs. The lines shown are intended to be a guide and do not represent a fit to the experimental data.
